This bottom photo is what I did for Lithium for the Periodic table swap. Lithium is found in batteries and mood stabilization medication among other things. I decided to parody those colorful ipod ads with someone who was listening to their ipod and suffering from depression. These cards had to have an atomic number so I carved a 3 inside an apple.
Below is the filing system I used to sort the element cards and a picture of me packing up cards. What a mess! Alex and I sorted over 10,000 cards, but it wasn't brain bending at all. I was like dealing cards into slots. I had bags and bags of bubbled envelopes.
