AAAHHH!!!!!! It's an alien invasion!!!! That's what people would say if you launched these into the sky. All it is is a balloon filled with helium with LED lights dropped into the balloon. First, you need to get the materials. You need a balloon, of course, LED lights, disc batteries, string, duct tape, and a helium source. First, you need to put the LED lights into the balloon, but, the LED lights will not work without a power source. This is where the duct tape comes in. Attach the disc batteries to the 2 prongs on the LED and secure it with duct tape. The LED should be lighting up. Next, drop the LEDs into the balloon. The last thing you need to do is to fill the balloon with helium and then tie the end to some string so it won't stay floating forever. PLEASE HAVE AN ADULT HELP YOU WITH THE HELIUM!!!!!!!! It would be best to let these fly out on a clear night. Thank You and Try It!!!!!
