felecia187 this is easy and maybe someone has already done it who really knows , you get a weather balloon and before you blow it up with helium you put a couple of hundred glow sticks into the balloon after you break the glow sticks so that they will glow then you put in the helium , and when this baby gets airborne you do this at night so you can do your video and say that you saw a real UFO and no one will be any wiser enjoy .
