"Break a glow stick and put in clear nail polish." DO NOT DO THIS HOLY CRAP! There are some toxic chemicals in glow sticks that have not been tested on nails. They make glow in the dark polish that is safe, just buy some.
MAKE GLOW IN THE DARK ICE CUBES? Mix tonic water with a bit of water and put in an ice cube tray. Put in freezer until frozen. Get a UV or blacklight. The ice cubes will glow because of the tonic water TIP use plastic cups for added glow effect
