This handy Science Saturday’s experiment is from Preschool Powl and we found to be quite fascinating and easy to do.
You can learn about safe acids and bases you have around the kitchen. What combination bubbles the most? What combination fills the glove the fastest? Common acids include vinegar, pickle juice, lemons, and lemonade. Common bases include baking soda and antacids. Baking powder and Alka Seltzer have both an acid and a base that mix when the powder/tablet dissolves.
1. Carefully tie the fingers of the glove into a loose knot.
2. Let your preschooler spoon about 1 1/2 teaspoons baking soda inside the glove.
3. Fill the bottle about 1/3 full of vinegar.
4. Without letting the baking soda fall in the bottle, tape the glove to the opening of the bottle. Make sure the connection between the glove and the bottle is air-tight! Use your helpers to make this part easy!
5. Let your child dump the baking soda into the bottle, and watch the “magic!”
** Put your bottle in a tub or near the sink to catch any spills! **
When baking soda (a base) and vinegar (an acid) touch each other, they react and make carbon dioxide. Carbon dioxide is a gas that bubbles up the bottle and fills the glove.
