Kids like to see things explode and with this easy experiment they can watch the bags fill with gas and pop in front of them.
Here’s what you need
• Plastic Bags (we used medium size Ziploc bags and doubled the amount of vinegar and baking soda)
• Food Coloring
• 1/3 cup Vinegar (for each bag)
• 2 Tbsp Baking Soda (for each bag)
• Safety glasses
Pour the vinegar into a bag and add food coloring to it.
Twist the baggie just above the liquid (make sure to leave room at the top for the baking soda) and secure with a clothespin.
Add the baking soda to the empty space and seal the bag.
When ready, remove the clothespin and allow the baking soda to fall into the vinegar. Watch as the bags fill with gas and explode in a fizzing mess!
It took us a couple of tries to figure out the right amount needed for our bag size. We also discovered that if we add less vinegar to the baking soda it creates a fun sand mixture that the kids enjoyed playing with.
