Next time you have a school sanger, don't toss the bag, take it home and try this!

What You Need:
- snap-lock sandwich bag
- warm water
- vinegar
- measuring cup
- baking soda
- teaspoon
- tissue

What To Do:

1. You're about to make a mess, so if you wanna avoid getting busted, head outside!

2. Pour 1/4 cup of warm water and 1/2 cup vinegar into the sandwich bag, then zip it up halfway.

3. Now make your baking soda bomb - put three teaspoons of baking soda into the middle of the tissue and fold in the corners to wrap it up.

4. Drop the baking soda bomb into the sandwich bag, and zip it up tight.

5. Put it on the ground, take a few steps back and watch it go from bag to BANG!
