Why Do I Buy this Random Shit?

So a couple of weeks ago, I bought this:

It was an impulse buy, but one of the guys I work with bought one too. We both set them up, and are now in a heated battle to see who can grow a plant faster. It sounds a lot stupider when you read than when we made the original bet.

The silly thing is, it fascinates me. I have little plants growing in my room, that will someday be able to eat most species of small bugs. And watching them grow is really an odd thing to see. I've never grown a plant from a seed before, so it strikes me as very odd that I can grow these little things, since apparently they are hard to care for.

Anyway, comment away, let me know random shit you buy.
