In this instructable I will show you how to make refrigerator magnets for the lab geek. Why not decorate the fridge with petri dishes growing molds and bacteria. Well maybe that is not such a great idea (don't worry, these cute magnets for the fridge don't really contain any cultures).
I work in a lab that does tissue culture and we had some old petri dishes lying around that we no longer were using, so I took a bunch home. I'm still not sure what to do with all of the dishes, though this seemed like a fun way to use some of them.
