Let’s make a snowman toot ☃️💨🤭
Follow for 12 days of science mischief 😉
📝HOW TO
1️⃣Put 2 tablespoons of baking soda in a Ziploc bag (I recommend the name brand ones! Off brand can sometimes have invisible holes at the seems)
2️⃣Put 1 cup vinegar in a different Ziploc bag – don’t zip it up, and place it in your bag of baking soda
3️⃣ zip the baking soda bag TIGHT and tape it onto your snowman
🫨NOW SHAKE
🎄🧪 THE SCIENCE 🤓
Baking soda is a base. Vinegar is an acid. When you mix the two together, you kickstart an acid-base chemical reaction that creates carbon dioxide bubbles.
🫧Those bubbles build and build and build, which means the pressure builds and builds and builds.
💨Once the bag can’t take the pressure anymore -> it toots!! Releasing all the gas.
⚠️do this one in a container in case any liquid spills out (how embarrassing for the snowman 😳)
