Fizzle Balls!

At the Community Halloween Party the past 2 years I have had some type of weird science activity for the kids to be involved with. The recipes have come from a book that the boys have called "Kid Concoctions of Bibical Proportions." You can check out the website at www.kidconcoctions.com but we made "Fizzle Stones" (I called them Fizzle Balls) ahead of time with small Halloween prizes inside. These are simple and easy to make. For a small batch take 1/4 cup baking soda and add a little bit of water to make it into a dough. Then take the dough and place a small trinket into the dough and roll or press into a ball. You then need to let these dry overnight. Now once they are dry, Fill a glass or bowl with at least 3 cups of vinegar and let the kids carefully drop in the "Fizzle Balls". The reaction causes the foam to overflow and the trinket will be released from the ball. The kids thought this was great, but let me tell you it took about 8 POUNDS of baking soda to make enough for 100 kids (and we didn't use them all!) But the kids had a great time and it is simple science that can be found in your kitchen! Have fun and don't be afraid to make a mess with the kids - just make sure they help clean up too!!!
