Also make sure they don't throw them or shove them up their nose (Yes, stuck Skittles are hard to extract, ask me how I know..) The goal of this lab i

Did you know you can use Skittles candy to demonstrate absolute dating and radiometric decay! Buy a 1-4 lb bag at your local bulk warehouse store for savings. This lab is a great way to show how isotopes decay by shaking a plate full of random skittles. Students use Skittles to observe "Isotopes" decay over each half life. At the end of the lab ( and only IF they have done all their work) they can enjoy their "daughter products". Skittles were used because they are durable, hypoallergenic, an
