Bag Bomb....
One may think of acids and bases as harmful chemicals that white coated scientists keep locked away.
This experiment is a simple way of showing that a kitchen cupboaard has these chemical "secret agents" in abundance, And with just a little outlay in time and equipment, you can get "more bang for your buck!"
You will need
* a ziplok sandwich bag
* paper towel
* 1 1/2 Tablesppoons of baking soda
* 1/2 cup of vinegar
* 1/4 cup of warm water
Then...*This experiment will only work if the sandwich bag has no holes in it. Test it by filling it with water, zipping it shut, and turning it upside down over the sink.If no water leaks out, you are fine. Empty the test water from the bag. If you have leakage, repeat the process until you find a bag that has no leaks.
* Tear a sheet of paper towel into a 6 X 6" square.
* Pour the baking soda onto the center of the paper towel, then fold the paper towel into an "envelope" with the powder inside it.
* Pour the vinegar and warm water into the bag.
* Carefully and quickly, add the "paper towel" envelope to the bag and seal it.
* Shake the bag a little, then place it on the ground and STAND BACK!
* The bag will inflate and POP with a satisfying BANG!!!!|
