If Nikola Tesla were alive he'd be sporting this lovely chocolate brown and sepia T-shirt, especially because it glows in the dark. (Just like he probably did.) Below his GITD name is his face and below that are photos and patent sketches of his major inventions. 100% cotton. You pick the size.

That'd fill this 9-oz ceramic coffee mug with the periodic table of elements printed on the side to about half a cup. It's printed in color on both sides, actually, in case you're left-handed. The atomic numbers and weights are a trifle small, but then they are atomic.

What's three feet tall and wears a white coat? A kid in a chemistry lab, and don't drink the sparkling water. Dress them right for everything from lab sciences to art projects. Our child-size lab coats are white cotton polyester, 4-button and hip length, with notched lapels, one breast pocket and two side pockets. You pick size 4, 22" long from collar to hem; size 8/10, 26" long; and size 12/14, 28" long.

We have come into a cache of very nice short-sleeved lab coats, made for pharmacists. They're a white 80% polyester / 20% cotton blend with (1) breast pocket (left) and (2) waist pockets. They're 30" to 32" long, collar to hem, with lapels and 3-button fronts. Some are plain but most have a small logo identifying a pharmacy on the right breast. Mighty nice lab coats or painter's smocks.

Because nothing says high fashion like flashspun high-density polyethylene fibers. Made by DuPont. We've gots some nice extra-large pants, all with very elastic waists. 24" waist and 47" long. Great for paint, garden work or giving the dog a bath.
