If you’ve been at a party at night, you might have trouble finding a drink in a cooler. Is that can bobbing in the ice water beer or soft drink? Put a glow stick in the water and light up the entire container.

Glowsticks are waterproof and last for hours. They won't give off heat and melt the ice. Best of all, the sticks give the cooler a nice eerie glow.
