I don’t know about you, but I spend way too much time on Pinterest! I have a tendency to “pin” things and never do them (well, I make a lot of recipes, but that’s for another blog!).
So, I’m going to start a feature here on the Science Adventure Club blog in which I do a cool science experiment from Pinterest with my kids, once a month. I hope you’ll join along!
This month, we’re doing the “Exploding Bag” experiment found on this blog.
Here is the supply list:
- Paper towel
- 1/2 c. vinegar
- 1/4 c. warm water
- 1 1/2 T baking soda
Here’s how you conduct the experiment:
- Cut the paper towel into a smallish square
- Put the baking soda into the paper towel square, and fold up into a little packet
- Put the water and vinegar into a sandwich size ziplock bag. Zip it halfway closed.
- Sneak the baking soda packet into the bag and quickly zip it the rest of the way closed.
- Wait, watch, and BOOM!
This isn’t all fun and games, boys and girls! This is chemistry AND physics! Here’s what’s happening:
Vinegar and baking soda join together to create an acid/base reaction (chemistry). When mixed together, they create carbon dioxide. The bag fills up with the carbon dioxide until it can’t contain it anymore (physics!), and the bag explodes.
Here’s a link to my “Science” board on Pinterest. If you have a science or nature study page on Pinterest, please PLEASE post a link below!
Did you do a blog post of your family doing this experiment? Feel free to post a link to that, too.
