How to Create a Reaction in a Bag of Snow

I drew a snowman face on our Ziploc bag, just to make it cuter. Fill it up with snow, but don’t pack it in tight, just fill it loosely. Before you seal the bag, add in a few Alka seltzer.

We watched it inflate over a period of about an hour. It slowly expanded as the snow melted and caused a reaction with the Alka Seltzer.

You could definitely add more Alka-Seltzer tablets to make the bag pop if you'd like.
