Exploding Watermelons

I love Halloween. One of my favorite activities is to “carve” pumpkins using a simple reation inside the fruit. First, you carve the face then carefully replace pieces. After creating a reaction by generating a gas inside and igniting it (ask your local chemistry teacher for the details) the face pieces are blown off with a small explosion. Halloween is more than 100 days away and I just couldn’t wait. So I initiated the new weather anchor at the local Denver television station by introducing her to carving watermelons. The problem was, we didn’t really carve the watermelon, it exploded. Watch the Video to see how we skipped right over the carving and went straight to exploding.

Our week-long salute to amazing science teachers wraps up with a visit to Heritage High School in Littleton, Colorado, where chemistry teacher Wally Keesecker gets students fired up about science. Wally is well-known for his attention-grabbing science demos that introduce students to real-world connections to everyday chemistry. Video: The Steve Spangler Mad Scientist Tour finishes the week with a bang at Heritage High School. 6 a.m. October 7, 2005. This is an especially fun visit for Steve since Wally Keesecker was his 8th grade science teacher in the Littleton Public Schools. “People like me make the decision to go into education after being inspired by an amazing teacher. While I didn’t exactly know that I would one day become a science teacher, I knew that I wanted to do something in education after experiencing someone as amazing as Wally Keesecker,” says Steve Spangler who is like a kid in a candy store whenever he pays a visit to his former science teacher. Wally and his teaching colleagues dazzled us with two demonstrations centered around a Halloween theme. The first demo illustrated a chemical reaction that oozed from the eyes and mouth of a carved pumpkin. Because …
