Tomorrow starts the new semester for me, and I finished my course prep (well, tomorrow’s activities anyway) so I figured I would celebrate with a little creativity. Not too long ago, I came across the activity where you can make a t-shirt iron on by drawing on sandpaper. I have sandpaper, some old t-shirts and I splurged on an 8-pack of crayons ($0.67 at Walmart) so I figured I would give it a go.

This year is all about the periodic table, so I wanted a periodic table design. One trend that I particularly like is the number of stable isotopes, which very clearly shows off my favorite element – technetium – because it is the lightest element without any stable isotopes. Technetium’s claim to fame is that it’s the first element to have been synthesized (in 1937) and therefore it is, in my opinion, the element of makers.
