Glowsticks

I had lunch with a friend who has a good business selling glowsticks. These are the glowsticks that you'd be likely to see at a kids party, or wanna be kids wearing all different colors at a rave. There is also a whole subculture of video sites, of people dancing with glowsticks on and making patterns. From a business standpoint, I was fascinated by how relatively inexpensive they are... cases of 2-300 for $75. That probably explains all the vendors out on the fourth of July selling them :)
