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.
Step 1: What you will need
- Petri dishes - you can pick these up at science supply stores (for example)
- Sharpies and paint
- Neodymium magnets
- white paper
