Prepare for Halloween with this fun Count Popula experiment! See if you can blow up your own balloon Dracula without touching it? *PLEASE NOTE: THIS EXPERIMENT IS SUITABLE FOR 6-12 YRS. AN ADULT MUST BE PRESENT AND SUPERVISE CHILDREN AT ALL TIMES*
YOU WILL NEED:
Small plastic bottle
Funnel (or piece of paper)
Black permanent pen
Start off by making Dracula. Using black, white, and red felt, make an outfit similar to the image above. Use the black felt to cut out a cape and glue to the back of the bottle. Cut an oval out of white felt to make a shirt and finally cut a small red bow tie and stick to the top of the white felt.
On a balloon, draw Dracula’s face with a black permanent pen.
Using a funnel, add 1 teaspoon of citric acid to the bottle. Next, use the funnel to add 1 teaspoon of Sodium Hydrogen Carbonate.
Stretch the balloon over the mouth of the bottle and let the baking soda fall into the water mixture in the bottle. Watch your Count Pop-ula expand! *To avoid mess, try this step outside*
THE METHOD BEHIND THE EXPERIMENT
Sodium Hydrogen Carbonate and citric acid mixture creates a gas, carbon dioxide, which fills the balloon!
