Picture of Geeky Fridge Magnets

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.

Step 1: What you will need

Picture of What you will need
  • Petri dishes - you can pick these up at science supply stores (for example)
  • Glue
  • Sharpies and paint
  • Neodymium magnets
  • white paper

I recommend to use some white double-sided adhesive tape on the dish, put the magnet on it and put some single-sided tape over it all...this magnet will never part by itself (depending on tape quality of course).

Cool, thanks for the advice.

Of course the flatter the magnet is, the easier it is to fix the single-sided tape on top. But as neodym is so strong, there will be no problem taking a really flat one...perhaps if necessary larger but thinner like e.g. 10mm x 1mm!?!

Hi, I am an admin in a geology lab workplace, so I am not overly sure if this would work, but I have seen small, round plastic containers at craft and dollar stores that are often used to hold "seed beads". They are quite cheap and kind-of look like petri dishes. It might be an option for those who want the look but not the cost of a specialty lab products store.

Great idea! Thanks for the tip.

As a fellow lab rat (E-coli and yeast cultures) I applaud this idea. Although I would hate to take work home with me...

Yes, perhaps I should have saved this one for Halloween.
