Dancing raisins

Dancing raisins

Make your fruit dance!

We're in the mood for dancing...

We showed you how to make your own raisins. Now you can make them dance!

What you need:

  • Tall, clear glass
  • Raisins
  • Fizzy lemonade - it won't work if the lemonade is flat

How to:

  1. Gently pour the lemonade into the glass.
  2. Add a few raisins and wait for a few seconds.

What's happening? Can you see the raisins moving up and down in the glass?

Experiment with other types of food. Try pasta, popcorn or other fruit. How heavy does something have to be before it won't dance in the lemonade? Make sure you use fizzy lemonade every time!

What's happening?

The fizz in your lemonade is carbon dioxide. Bubbles of carbon dioxide form around the edge of your raisins.

The bubbles stick to the raisins and get bigger. Eventually, the bubbles are big enough to make the raisins to float - a bit like you wearing arm bands in the swimming pool.

When the raisins get to the surface of the glass, some of the bubbles pop and the raisins sink.

The raisins keep moving up and down until most of the carbon dioxide is gone from the lemonade and the lemonade is flat.
