Just call it the Halloween After-Glow. No, it’s not the warm feeling you get in your heart when you think of all of those darling little Trick-or-Treaters or think of the fun kids had opening their candy. The “After-Glow” refers to the light coming from inside the pumpkin after the kaboom! Hundreds of chemistry teachers from across this great land of ours joined together yesterday to share their favorite Halloween science demonstrations.
Here’s your next question… How do you do it? Since this is a classic chemistry teacher demonstration, it’s best to consult your favorite chemistry teacher or let your fingers do a little “googling” to research the various ways to produce the small amount of acetylene gas in the pumpkin… or just read through the comments below.
Editor’s Note: This experiment was presented in this forum for educational purposes only. We DO NOT recommend trying this experiment in the classroom unless you have had proper training to do so. Please note that Steve Spangler Science takes no responsibility for comments posted on this site.
On a personal note, I know that Steve practiced this experiment at least 20-30 times with trained professionals, in a controlled environment, before presenting the experiment on the air. Even for television, the experiment was performed with safety personnel and fire officials on-site. This is not a do-it-yourself activity.
Please have a safe and happy Halloween – the Editor
