You will need:
- Baking Soda
- Warm water
- measuring cups
- paper towels
- plastic bags.
First, cut squares of paper towels and add about 1 1/2 to 2 tsp of baking soda
Wrap them up like a little packet
Then have the kids help you add about 1 cup of vinegar and 1/2 cup of warm water
This is the tricky part: drop the baking soda packets into the bag and IMMEDIATELY seal the bag. If you take too long to seal the bag and the baking soda starts to fizzle it may not explode. They will start to blow....
