This is a cool trick you can do with just duct tape. All you have to do is stick two sides of duct tape together and pull them apart! This produces an effect called triboluminescence. This same effect can be made by chewing wintergreen life savers.
This was NOT my idea, there are quite a lot of You Tube videos on it.
Step 1: Parts/Tools
Duct tape (3M brand seems to work the best)
A working pair of hands
Step 2: Prep Work
Take a strip of duct tape and fold over each end to make a tab so that you have a place to hold on to when you rip it apart. Then, fold it in half on to itself. I've found that the bigger you make the tabs, the easier it is to pull the tape apart. You don't need to have as much duct tape as I do.
Step 3: The Trick
Go into a dark room, preferably with a mirror so that you can see the duct tape better, and pull the tape apart. The faster you pull the duct tape, the brighter the glow. Unfortunately, I was not able to get a good video of this with my camera. Have fun!
