Pinteresting! Exploding Bag.

DSCN3961

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!

The reaction to the reaction.

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.

Have fun!!

Did you do a blog post of your family doing this experiment?  Feel free to post a link to that, too.
