Bag Bombs

Today in science, we created bag bombs! They were a lot of fun to make, and a few of the students mentioned they would like to do them at home. All you need is a Ziploc bag, baking soda, vinegar, water, and a tissue. In the bag, add 1/4 cup warm water to 1/2 cup vinegar. Next, spread a tissue out and add 3 teaspoons of baking soda. Bunch up the tissue to hold the baking soda. Close the bag most of the way and leave enough space to slip in the tissue packet. Drop in the tissue, seal the bag (it is important to get a good seal), give the bag a little shake, and toss it! Toss it somewhere soft so the impact doesn't cause the explosion. In addition to making great scientific guesses, the students also practiced science safety by using their goggles! I originally found this experiment at the  E is for Explore blog.
