A fun experiment that'll get your boys and girls bursting with excitement.

--WHAT YOU'LL NEED--

Baking pan or bowl
Ziploc sandwich bags
Baking soda pouches
1/3 cup vinegar

--STEP 1--

Measure 1 rounded tablespoon of baking soda into a square of single-ply toilet paper. Fold horizontally and secure with a small piece of tape, then fold vertically and wrap it all the way around with a large piece of tape, ensuring it will stay closed.

--STEP 2--

Measure out 1/3 cup of vinegar and pour it into the bag. Then close the bag so it doesn't spill.

--STEP 3--

Open the bag slightly to allow an empty portion to hang over the edge of pan and add the baking soda pouch so that it does not touch the vinegar.

---STEP 4--

Zip the bag shut without mixing the chemicals yet.

--STEP 5--

Lift the bag, allowing the chemicals to mix. Shake 3 times, place in pan or bowl and observe what happens.

--HOW IT WORKS--

When the baking soda and vinegar mix, it results in a chemical reaction that produces carbon dioxide (CO2) along with water (H2O) and sodium acetate. If the bag is properly sealed, the carbon dioxide is trapped and fills the bag until it cannot hold any more, at which point it pops!
