"Here's the big daddy of all my atom inspried listings.. The Carbon Kit! It comes with 6 protons (red) 6 neutrons (green) and 6 electrons (blue)! Use the set to build up any atom from hydrogen (1) to carbon (6)!
The green particles and blue particles do have eyes, but they're made with black wool and a little harder to see. The green and red balls are 1 inch in diameter, the smaller blue ones are 3/4 inch in diameter.
They can be used as tools to get kids enthused about the atom, split into 6 sets of one blue, one green, and one red as geeky party favors, or live on a science-lover's desk top. I can also E-mail short scripts of sciencey jokes I've made up for them to say."
