- Two CR2032 3V lithium coin batteries
- Duct tape
- A balloon

Attach batteries to an LED
Place two CR2032 3V lithium coin batteries on top of each other, then place them between the prongs of a ten-millimeter non-diffused LED. Secure with duct tape.
Put inside balloon
Push the LED-battery pack inside an uninflated balloon.
Fill with helium
Blow up the balloon or fill it with helium. Disposable helium tanks can be purchased at party supply stores.
Make a statement
For an impressive display, get some friends involved so you can fill a few dozen balloons.
Decorate with balloons
Use LED floaties to decorate your next party. Shape them into an arch or canopy; line your walkway with them; place a few on each table as a centerpiece; or create a classic ceiling balloon drop.
