Nuclear Gardening: Mutating Plants with Gamma Radiation (or watch me fail at Gardening;)
Disclaimer: This is not a very smart Experiment, but i wanted to try something like this for a while, and it was kind of amusing in the end ;) But dont do this at Home exept you really know what you are doing!
Basically i irradiated some Plant Seeds with Gamma Radiation and let them grow beside a non irradiated Control Group.
