Maybe you're not quite sure what an LED balloon is. But they're very popular right now — at birthday parties, weddings, holiday events.
It's actually a regular balloon with a string of multicolored LED light wrapped around it. The lights are usually powered by two AA batteries, stored in the plastic handle attached to the balloon, which is inflated with helium or an air pump. When you turn the lights on, they glow and flash.
"They are gorgeous," proclaimed Rachael Ray when she showed off the balloons on her talk show last spring.
