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

  • Petri dishes - you can pick these up at science supply stores (for example)
  • Glue
  • Sharpies and paint
  • Neodymium magnets
  • white paper
<p>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).</p><p>Pic:</p><p>1) single-sided</p><p>2) magnet</p><p>3) double-sided</p>
<p>Cool, thanks for the advice.</p>
<p>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!?!</p><p>:-)</p>
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 &quot;seed beads&quot;. 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...
That's just awesome!
Horrors of radioactive Doom barrel slick sticking to a Geek revisited :-o
Yes, perhaps I should have saved this one for Halloween.
What an unusual idea! Thanks for sharing!<br>sunshiine
Awesome!<br />"Mutant bacteria trying to escape" - love!
