Check out our updated list of spooky science Halloween Activities here! 
Worried about having too much Halloween candy laying around? Here’s a little science you can do with your kids’ haul—or your own!

Chances are if you’ve got kids they’re going to want to go trick-or-treating. This means they’ll end up loaded with way more candy than you’d want them to actually eat. What could you do with the rest? Well, you could donate it, you could take it to a candy buyback program or you could do a little science with it! Here are a few ideas from Candyexperiments.com.

Lifesaver Lights
Here’s a simple one. Grab some wintergreen flavored Life Saver candies, stand in a dark room, face a mirror and chew them with your mouth open. You’ll see flashes of light that result from electrons in the candy; these are more easily visible thanks to the wintergreen flavoring.

 

 

Pop Rocks
Ever tried pouring some Pop Rocks into a glass of water? If you do, you’ll find that it’s a pretty effervescent experience.

 

 

 

Chocolate Bloom
By rapidly heating and cooling a piece of chocolate, you can gradually seperate it into its component parts. This results in white streaks and spirals called chocolate bloom. You can even still eat the chocolate once this is done—the texture might be a little unusual but it’s still perfectly edible!

 

Density Rainbow
Skittles are both delicious and colorful – here’s a way to really help that color shine. By using different quantities of various colored Skittles and the principle that sugar makes water more dense, you can create a liquid rainbow. This is one of the tougher experiments to try; make sure you pour the melted Skittles very slowly otherwise the different colors will just mix together.

 

Color Separation- Chromotography
Even if a piece of candy is only one color, that color can actually contain a variety of differently colored dyes. By dissolving candy coloring into water then slowly dripping that water down a piece of paper, it’s possible to see all those various colors. This is an easy experiment and the results are striking. Try it with brown M&Ms!
