Revenge of the Red Gummi Bear

Posted 01/27/08 by don | Filed under: justRemarkable | 1 comment

Who would ever think of innocent looking gummi bears as incendiary material. Apparently, mixed with molten potassium chlorate, just one red gummi bear can cause a rather violent reaction.

Here's an explanation from a teaching resource, originating from Queen's University's teachers' college.
Potassium chlorate (KClO3) is a powerful oxidizer, used in matches and fireworks. Sucrose is an easy-to-oxidize energy source. Candy is composed primarily of sucrose.

Here is the chemical equation for the reaction: 2KClO3(s) ?> 2KCl(s) + 3O2(g)

BTW, did anyone else notice the bottles of other chemicals littered around the lab bench? If you're prepping a demo of a violent reaction, shouldn't you clear the area around your setup as a precaution?
