# How to make raisins dance

## Simple Instructions & Video Tutorial

Ready to make some raisins dance?? Although you won’t need to buy them dancing shoes, once you give your raisins some soda pop, they’ll start dancing for you with every bubble!

In this easy science experiment, your young scientists will learn about the effects of density and buoyancy. Below you will find a demonstration video, a supply list, and printable instructions. Suitable and fun for all ages.

### Supplies Needed

• Clear Drinking Glass
• Clear Pop like Sprite or 7Up
• Raisins

### Dancing Raisins Science Experiment Instructions

Step 1 – Gather your materials together and begin by pouring the pop into the cup. Pour until it is about 3/4 of the way full.

As you are pouring the pop, take a moment to make observations. What did you notice as you poured the pop into the cup? Did you see anything interesting happen? Did you hear anything as you poured the pop into the cup?

What do you think will happen if you place the raisins into the cup? Write down your hypothesis (prediction) and then continue the experiment to test it out and to find out if you were correct.

Step 2 – Next, take a handful of raisins (approximately 10-15) and carefully place them into the cup. Then take a step back and look through the side of the cup to watch what happens.

Step 3 – What initially happened to the raisins? Did they sink to the bottom? Did they float to the top? As you observe the cup for a few minutes, did anything else happen? Was your hypothesis correct?

Do you know what caused the raisins to “dance” and move up and down in the pop? Find out the answer in the how does this experiment work section below. It also contains ideas on how you can expand on the experiment.

### How Does the Science Experiment Work?

When you first place the raisins in the soda, the raisins sink because they are denser than the soda. As the carbon dioxide gas bubbles dissolved in the soda attach to the wrinkled surface of the raisins, the raisins begin to rise. The raisins rise because the soda bubbles help increase the buoyancy of the raisins.

Buoyancy is the tendency of an object to float in fluids because of the upward force fluid exert on objects.

This increase in buoyancy helps the raisins become less dense than the soda. When the raisins get to the surface of the soda, the carbon dioxide bubbles surrounding the raisins pop. The raisins lose buoyancy and become denser than the soda so they begin to sink. As the raisins sink, more carbon dioxide bubbles will attach to the raisins’ wrinkled surface, starting the process all over again!

The raisins will continue to dance (sink and float) in the soda until all of the carbon dioxide bubbles have popped and the soda becomes “flat”.

### More Science Fun

Try this same experiment with objects that do not have a wrinkled surface like blueberries or grapes. Do they rise in the soda the same way the raisins did?

Instead of using soda like 7Up or Sprite, try using baking soda dissolved in water and vinegar. Dissolve two teaspoons of baking soda into a half cup of water. Add 6-7 raisins to the baking soda/water solution. Slowly pour a tablespoon of vinegar into the mixture and watch the raisins dance! (This version of the experiment could make a mess, so put your cup into a shallow dish, like a pie pan, before adding the vinegar).

I hope you enjoyed the experiment. Here are some printable instructions:

SO try this baking soda and vinegar experiments and have some science fun today!

### Dancing Raisins

This dancing raisins experiment is always a huge success because it is easy to try, teaches, and leaves a lasting impression. Try this science activities for preschoolers, toddlers, kindergartners, and grade 1 students to teach about the baking soda and vinegar reaction. There are LOTS of baking soda vinegar experiment ideas from blowing up balloons to volcanos, our dancing raisins, and more. So try several and help kids really understand while having fun because science is so much fun! If you understand the underlying principles, everyday items can be made to behave in strange and unusual ways.

### Dancing Raisins Experiment

This Dancing Raisins Science Experiment uses the same chemical reaction behind the well-known homemade volcano project and the self-inflating balloon experiment. When vinegar (an acid) reacts with baking soda (a base) one of the products of the chemical reaction is carbon dioxide, a gas. In the volcano, the gas creates a bubbly solution which comes oozing out of the volcano. For the balloon experiment, the gas fills up the balloon. This dancing raisins science experiment has a more subtle effect, but still impressive.

Basically, by adding baking soda and vinegar to another liquid, like water, the liquid becomes filled with many bubbles which rise to the surface and pop. If a light object is placed inside the liquid, such as raisins or peanuts, the bubbles stick to the surface of the light objects, increasing their buoyancy, and causing them to rise to the surface with the bubbles. When the bubbles pop at the surface of the liquid, the objects, which on their own are more dense than the liquid, then fall back to the bottom. On the way down and while sitting on the bottom, they collect more bubbles, causing the process to repeat for several minutes. Eventually, either enough of the reactants will be used up to stop the process or enough air bubbles will get trapped inside the raisins to make them remain floating on the surface.

### Dancing raisin experiment

All you need are a few simple supplies to try this chemical reaction experiment that usese baking soda and vinegar to create a truly memorable, WOW experiment for kids!

Materials

• A clear drinking glass half-filled with water

## how to make a substitute for wine yeast

Everyone knows that the reason for alcoholic fermentation is the transformation of juice (fruit or berry) into wine. Without a certain type of yeast microorganisms, no fermentation, of course, will work. Very often, taking one or another berry in your hand, you will notice that its surface is covered with a white coating, which is wild yeast. But it also happens that after a long torrential rain, the plaque is simply washed off from the entire surface. Then wild yeast is either not enough, or not at all. In such a case, it is necessary to help the fermentation process. Help will consist in feeding the must with sourdough (wine yeast, in other words).

Sourdough ingredients can be any unwashed berries. Usually they take raspberries, strawberries and freshly picked grapes. And in this article we will try to prepare a starter from raisins, because you can use raisins at any time of the year. It does not depend on a certain ripening period, like certain berries.

Raisin starter will serve for wine from grapes, apples, cherries, other fruits and berries. Especially expedient is the use of sourdough. If any contamination is visible on the surface of the raw material, then it is necessary, of course, to proceed with water procedures. This can be done safely, because raisins have enough fermentative power. Despite the fact that we will wash off all the wild yeast from the raw materials, active alcoholic fermentation will occur. And now about everything in more detail.

### How does the must fermentation process take place?

Throughout the entire time, the process of fermentation of wine must is dynamic (not the same).

In the first stage, fermentation is very active. During fermentation, the yeast processes all the sugar that exists in the wort, and carbon dioxide and alcohol will be the predominant products of processing. While the sugar is being processed, the yeast will multiply vigorously. At the same time, there will be a strong release of carbon dioxide. The wort will begin to foam. For everything to happen this way, it is necessary to observe the same temperature. Otherwise, the quality of homemade wine will leave much to be desired.

The fermentation temperature directly depends on the type of wine you want to produce, the type of yeast used and the raw materials. On average, the interval is from 15 to 26 degrees Celsius. At temperatures below the above, the vital activity of the yeast stops along with fermentation. A high temperature (above 32 degrees) completely kills the yeast.

The first vigorous fermentation is called top fermentation. Gradually, the wort is clarified, when the amount of sugars remains less, and they begin to fall, and, following the sugar, the yeast begins to go down.

After 2-4 weeks of fermentation, the light must must be poured. Winemakers call this process “draining the sediment”. This must be done very carefully. Without disturbing the sediment, the young wine should be poured with a hose into a container similar to the previous one, which will be lower. The content of alcohol, sugar and measurement of the density of the wine occurs precisely at this stage. Next, the sediment that remains undisturbed is poured into a separate container and allowed to settle. Then add to the main volume. All this is done so that dead yeast cells do not get into the wine. If this procedure is not carried out, the taste of the wine will not be the same. Now the wine is again put under a water seal for further fermentation. Soon, after 4-7 weeks, the sediment is removed in the same way for the second time.

This is followed by a phase of slow fermentation. It is called bottom fermentation, as it takes place at the very bottom of the tank. Right now the wine is ripening. Sugar is still contained in the drink, but a clear wine taste has already been acquired. This stage of fermentation lasts 3-5 months, during which the wine fully acquires a rich taste and aroma, and the remaining sugar is processed by yeast. Next, we check the alcohol and sugar content, and bottle it, close it with corks using a portable capper.

### What can be used as a substitute for wine culture yeast at home?

Baker's yeast bought in a regular store is not suitable for making wine. You will need certain strains - wine yeast. It is they who have the unique property of preserving the taste and aroma of raw materials, and, like everyone else, they process sugar into alcohol.

Wine yeast can be made at home or purchased from the store. Do-it-yourself wine yeast can be prepared:

### Easy raspberry wine yeast recipe

Raspberries ripen early, which is why they are valuable. Raspberry starter can be made long before other fruits and berries ripen. Another plus is the number of certain bacteria living on the surface of the raspberries that can ensure fermentation. No one argues that other berries also have such bacteria, but their number is much lower.

Not every raspberry will ferment, alas. You need to choose only ripe and slightly overripe berries. Not suitable, of course, and washed berries. That is why you should not collect raspberries for such purposes even in the first days after the rain.

How to make wine yeast at home? Berries need to be collected and allowed to stand for a day. During this time, it will slightly sour, while you prepare all the other ingredients:

After the raspberry has been infused for a day, it needs to be kneaded. We turn the berries into a small gruel and fall asleep with sugar. Stir, add water. Mix again, then cover the jar with a cloth and put in a warm place, but protected from the sun, with a temperature of 22-26 degrees. Now for 4 days every 8 hours we open the fabric and gently mix the mixture. Otherwise, everything will turn sour or moldy. After this stage, take the gauze and squeeze out all the juice from the raspberries. Pour it into a glass container and put it in the refrigerator. Nothing will ferment there, and then, when the mixture is added to the wort, fermentation is activated.

### How to make your own raisin starter?

Raisin sourdough for wine is made at home only from high-quality dried grapes. First you need to select it. It is necessary to choose a variety where non-shiny berries of different sizes are very shriveled. In fact, most of the goods (currently raisins) that are supplied to the market or other retail outlets are dried and chemically treated, for example, with sulfur. Such a product looks very attractive, but the fungi that are on the surface disappear. For our purposes, this product is not suitable. The color of natural raisins can be both light and dark brown, and with a bluish tint. Ideal amber berries most likely have a lot of added preservatives in their composition. When falling, the berry should make exactly the same sound that a small pebble makes. It is necessary to purchase raisins for sourdough from grandmothers in the market or in organic food stores. And the best option would be your own blank.

To make wine yeast at home, we need:

First you need to sort out the raisins: moldy and damaged berries are useless to us. It is not necessary to wash, it is desirable to leave ponytails. We prepare an ordinary liter glass jar and a piece of gauze. We slightly heat the water and pour it into our jar. Dissolve sugar in it. We wait until the water has cooled to room temperature and pour the raisins there, stirring. We close the neck of the jar with a piece of gauze. We put the jar in a warm room for 5-6 days. All this time, the fungi will actively multiply until the process slows down and the finished fungi precipitate. The low quality of dried fruits will lead to the fermentation process that has not yet begun. After 5-6 days of inactivity, it is necessary to remove the raisins, and the remaining liquid is used as wine yeast from raisins at home.

### Technology for making homemade sourdough wine

We wrote about how to make sourdough at home with our own hands above, but what happens after removing it from the sediment? Further, the resulting liquid must be stored at a temperature not exceeding 15 degrees. This wine is ready to drink. White table wine, which will be consumed in spring and winter, must be stored in a narrow-necked bottle with a cork or barrel for another couple of months. Due to the rough taste of young wine, dry red wine is always aged for 2-3 months in the same barrels as white table wine. Then again remove from the sediment and bottle through a funnel with a filter. Such bottles are filled with wine up to half of the throat, corked and filled with sealing wax.

## Gypsy girls cook delicious food and love to dance (PHOTO)

On the International Gypsy Day, April 8, we went to visit the baron of the Cheboksary camp Artur Markovich.

### Preparation

So, in order to join the gypsy family, I decided to enter into character. The first thing I did was put on a gypsy skirt, blouse and even made a similar hairstyle. Going out into the street and standing for several minutes at a public transport stop, I realized that the image was a success - people shied away from me. For example, an elderly woman who got off the trolleybus said menacingly: "We already have Russian gypsies becoming."

### On the spot

To get to the Gypsy settlement, I had to go to the outskirts of the city - to the village of Algeshevo. They live there because they cannot afford more expensive housing.

### Children

These streets are very quiet, all the windows are covered with curtains, some of the huts have secret wooden doors. Suddenly, cheerful cries broke the silence, I turned around and saw gypsy children who were playing on a large snowy mountain.

### An Unusual Encounter

I got closer and I was immediately surrounded by about ten kids. They were poorly dressed, a little grimy, with old toys in their hands. There was something warm and at the same time cunning in their huge black eyes.

One five-year-old girl in a pink glittery dress began to look at the rhinestones on my bag with interest, another, older, sternly asked what I had forgotten here, and an older boy asked for candy. At that moment, I regretted that I had not even thought to grab the sweets. One of the children escorted me straight to the door of the chief gypsy of Cheboksary.

### Dwelling

Since childhood, my mother warned me against the gypsies, she told me with horror how they deceived my aunt, removing all the gold from her. And now, standing at the door of the baron, I could not even imagine what would happen to me - everything turned upside down inside. I knocked a couple of times, but no one answered. A couple of minutes later, Baron Artur Markovich came out and offered to enter. His whole family was there, and everyone greeted me kindly. Frankly, I was surprised by such a good reception.

### Life of the Gypsies

After a short conversation, I went to the kitchen to help the Gypsy girls with the housework. It turned out that the female sex is engaged in household chores almost all day. This is not easy to do, as they cook food and heat water in a large oven. Their diet is simple - as a rule, it is potatoes with meatballs, pasta and pancakes. On holidays, they arrange a feast, cook meat, bake pies. As a memento, I wrote down the recipe for Gypsy Pie.

### You can not change

At work, I managed to talk to the girl Stella. She shared with me that, according to the old tradition, she got married at the age of 15 and has been living with her husband for three years. Like many gypsies, she is not married for love, but she really wants children. Stella admitted that she never cheated on her husband - this is one of their main laws.

### Dancing

After cleaning the baron's daughter-in-law, Marina and her daughter suggested that I learn how to dance like a gypsy. A couple of minutes - and the music from an old DVD-player began to sound.
