Moshi-moshi mommies ;)

Wish you were in good condition.

This week’s experiment is another old classic which is still a lot of fun: Happy, “Dancing Raisins“.

Now that I think of it, it seems that most of the science tricks I did as a kid have become OLD classics.

Things You’ll Need:

Let’s make some raisins boogie!

Some of the raisins suddenly float upwards through the soda. When they reach the top, they sink again.

Soon, the raisins are dancing up and down in the glass.

What is going on? Watch carefully and you should be able to figure it out.
——————————————————–

Why it happened (explain to your toddler):

What happens? Can you guess why the raisins bob to the surface?
The baking soda reacted with vinegar to produce carbon dioxide gas.
This gas will collect on the uneven surfaces on the raisins.
When enough gas has collected, it will actually lift the raisins to the surface (kind of like little tiny parachutes) where the gas is then released into the air.
With the gas now gone, the raisins will sink back to the bottom where the process begins anew.

We have seen this experiment done with uncooked macaroni, but we find that raisins collect more bubbles and they are a lot more fun to eat ;)

You might try different kinds of soda. Soda with more fizz will cause the raisins to react more.
——————————————————–

Don’t forget to try this project with your toddler!

May Allah swt always blessed your family. Amin~
