Last weekend was SO MUCH FUN!! A good friend’s son turned 10 and requested a ‘Scientist Birthday Party’. The kids did several experiments, including Elephant Toothpaste, Blowing up a Balloon with baking soda and vinegar, Electromagnet, and a few others. My contribution to the fun was Fizzy Warts, aka ‘Fizzing Whizbees’.
I developed this fun experiment in College as a demo to do for kids in Chemistry Club Magic Shows.
The recipe is simple, the ingredients are easy to find and the result is– COMPLETELY GROSS!! Your kids are going to LOVE this!
PS- the warts taste like sour patch kids!
- 3 tsp citric acid (natural food store or by the canning stuff)
- 3 tsp meringue powder (crafts store by cake decorating supplies)
- 2 tsp baking soda
- 4 single serve envelopes green koolaid (sugar free)
Combine all ingredients in a jar. Make sure your baking soda is lump free!
To make a wart:
1. Place a few drops of water on the back of your hand.
2. Sprinkle a pinch of the powder on top and watch the wart fizz and grow.
3. Once the wart is nice and high, lick it off! The foam is sweet and sour like a sour patch kid.
You can experiment with different flavors of koolaid– red could be a fizzy boil!
We also tried putting 1 tbsp powder in a pint-sized jar and adding about 1/4 cup water. The foam filled the jar and the kids had fun eating it with a spoon.
HOW IT WORKS:
The water provides a medium for the baking soda, a base, and the citric acid, an acid, to react. The reaction produces carbon dioxide bubbles that are trapped by the powdered egg whites in the merigue powder, making a foam. Isn’t science fun?
