How to Make an LED Floatie

Light up your world with these beautiful and easy-to-make illuminated balloons. Inspired by the Instructables project:


  • Step 1: 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.
  • Step 2: Put inside balloon Push the LED-battery pack inside an uninflated balloon.
  • Step 3: Fill with helium Blow up the balloon or fill it with helium. Disposable helium tanks can be purchased at party supply stores.
  • TIP: To prevent a balloon-blowing headache, take a deep breath, then blow all the air into the balloon at once, keeping your cheeks flat and using your stomach muscles.
  • Step 4: Make a statement For an impressive display, get some friends involved so you can fill a few dozen balloons.
  • Step 5: 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.
  • FACT: A 13-year-old American boy blew up 213 balloons within an hour—with his nostrils!—in an attempt to set a world record.
