Happy 2020 STEM Sparkers! I think there's some 20-20 vision joke in there somewhere, but it's been a busy week here at STEM Spark, so my mind is a little melted (haha, that's a joke related to snowpeople, get it?). Anyway, this week Jack and I did a fun science experiment where we had a Ziplock bag burst because of carbon dioxide. And to make it more seasonal, we first drew snowmen (or maybe snowpeople?) faces on the Ziplocks. Read below on how to make your own exploding.
