Do you ever watch the discovery channel? Mythbusters in particular...

They had an episode that really peaked my interest. They set up greenhouses on top of their building and did some experiments with plants and music/talking.

Sounds crazy but the plants that listened to classical masterpieces and positive talking to from people actually did way better than the plants they played fast metal and screamed negative things at it.

They based the experiment on someone elses theories and experiements but I cant remember the name.

Very strange and interesting if you ask me!
