The Dancing Raisins Experiment

Today's experiment is another classic. 
I recall observing this one in elementary school myself! :)
It was still fun to watch these many years later.

Dancing Raisins Experiment

What? Dancing raisins? 
Yes! Didn't you know that raisins like to boogie?
No, well then turn up the music and get ready to witness
some fun as you watch raisins dance in this simple & fun experiment.


What You Need:
sprite/7-up or other clear soda
raisins
clear cup, bottle or other container


What To Do:
1. Add your clear soda to your container/bottle/cup
I filled our bottle about 1/3 of the way.

2. Drop in some raisins. 
How many? That is up you.


3. Make sure you have some music playing


& watch closely as those raisins get down! :)



For comparison we also did the experiment using plain water.

Ah, no fun dancing raisins this time. :( 

Why?

The science behind it - Raisins sink in water because they are more dense. Soda on the other hand has carbon dioxide and forms bubbles of gas. Those bubbles attach themselves to the raisins and make it float. When the bubbles pop, the dense raisins fall back to the bottom of the jar. This up and down motion caused by the bubbles makes the raisins appear to be dancing. FUN!

Who knew raisins were the life of the party?

    1. :) My list is long too! The girls have really shown interest in the fun science stuff so I am definitely going to be incorporating more of that with them. This was a lot of fun for us.

  3. When I was a kindergarten assistant teacher, we did this in our classroom. It is such an awesome experiment!

    1. I hope they enjoy it! Just be sure to have a generous supply of raisins for the "let's add more" and "let's do it again" that is inevitable! :)

  6. I wonder if it'd work the same using a different soda..........

    1. good question. I didn't try it because I wanted something clear that you could see through to observe the, but I imagine any fizzy soda would work since it's the carbonation that does the trick.

  9. Oh no. I must NOT show this to my son. I already have a container in the fridge with water and raisins sitting it (he is making cake apparently)... this would mean no end to our experiments ;-)

    Thanks for sharing on Kids Get Crafty!

  11. can it have no carbon dioxide? and it will still work

  12. Classic! Try a couple of twists on this great experiment:

    1. Craisins instead of Raisins. Craisins are slightly less dense and tend to dance faster & longer.

    2. Make your own fizz! Use water, a spoonful of citric acid crystals and a spoonful of baking soda. Making your own soda water doubles the content potential for this one.

    Awesome!!

  13. is this something we could do in individual bottles for them to take home. Will it keep working?

  14. This is a very fun experiment for preschoolers, thanks for the idea. I am wondering if you could use something other than raisins and still get the same results? As the National Association of Education for Young Children asks preschool teachers to not use food in activities. As to not promote "playing with food", since there are so many starving people in the world. I'm thinking maybe marbles or pennies might work? Any thoughts?
