Picture of Floating LED Lights
Instead of buying expensive pool LEDs from the store, you can make one in 15 minutes with a few materials. This is guaranteed to work, and is very simple to make.

Step 1: Gather The Materials

Picture of Gather The Materials
You will need a few materials to make this project.
1 small clear plastic bottle with the lid
1 LED
1 battery pack from a old flashlight
Aluminum foil
Glad Press-n-Seal wrap (or opaque Cling- Wrap)
Tape
Styrofoam

That's a great idea. It might be wise to use a plastic jar instead of a glass jar so you don't have invisible glass shards at the bottom of the pool in the unlikely event that one of your lights breaks.
Is the styrofoam necessary? I would think that a jar that large would displace enough water to float on its own.
For bonus points, you could use the guts out of one of those solar path lights, and then you could leave it in the pool 24/7!
I like your suggestion better--I feel extremely uncomfortable having glass near a pool.

Wouldn't it pay to also wrap the plastic wrap around the foil-covered lid so the aluminum would be protected from getting wet by accidental splashes or rain? Or to cover the entire unit in plastic?
