Now let me explain how we got here...
What you need:
- 1 sandwich baggie
- 1 paper towel
- 1 and 1/2 Tbs. of baking soda
- 1/2 cup of vinegar
- 1/4 cup of warm water
What to do:
- Tear the paper towel into 4 equal square pieces. For one baggie you will use 1 small square.
- Measure out the baking soda in the middle of the paper towel and fold the corners and sides in to make a pouch. This is your time-release packet. Set it aside.
- Measure out the liquid and pour in the baggie. So you have a baggie with the water and vinegar and a pouch with the baking soda.
- GO OUTSIDE for the actual experiment. Before we began, Busy and I talked about the reaction between vinegar and baking soda that we have seen before (when we made a volcano and did fizzy painted pumpkins). Then I asked what she thought would happen if all that fizz built up in the bag with no way out.
- Open the baggie and drop in the time-release packet and quickly zip up the baggie and place it on the ground. (We backed way back not knowing how big the pop would be. We clearly overestimated the power of the pop).
- Then POP! It explodes!
Note: I suggest making more than one of these :) With 1 paper towel, you can make 4 exploding baggies. I also recommend pouring water over the water/vinegar/baking soda. The soda will dry in a white mess if you don't.
