There’s just something amazing about dry ice – the solid that turns into a gas. Science teachers call it sublimation… kids call it amazing. Over the years I’ve presented a number of television segments about using dry ice to make Halloween even more fun – Screaming Ice, Bursting Smoke Bubbles, Spooky Apple Juice, the Crystal Bubble. This segment featured on the NBC affiliate in Denver is one of my favorites… probably because of the three little helpers.

Over twenty Denver-area home schooling moms visited the Steve Spangler Science laboratories this week for a special Halloween science workshop.
We have never done a workshop specifically for parents. Steve Spangler offers many opportunities for teachers across the country to take part in a science Boot Camp, but this was the first time parents were invited to come to our labs and learn how to bring more science into their lessons.
Steve Spangler offered the workshop as an opportunity to share some Halloween science experiments and activities with the moms (and one dad) to help enhance their science curriculum as well as give them the tools to go out and share with other parents.
After years of doing school science shows and student and teacher workshops, the Spangler Science team has come to understand the essence of what we do – we teach people to be amazing by providing them with products and innovations that are educational, entertaining, and inspire the imagination.

Hats off to Martha Stewart for job well done on her glow-in-the-dark pumpkins (okay, she called them funkins featured on October 26, 2007, on her television show. Our Media Product Coordinator, Brian Firooz, worked with the segment producer for several weeks to create a very cool effect using our Glow Powder and a little Martha Stewart creativity. The end result was a very cool glow-in-the-dark effect that was enhanced even more by using a black light.

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.
