You may already know we are big fans of Tattly, the way cool temporary tattoos we first told you about at their launch three years ago. (See? Ear to the ground over here.) Well, they’ve grown hugely since then with literally hundreds of designs, and now just in time for back to school, they are back front and center on our radar with the rad set of set of science tattoos.

This brand new set is made up of eight designs including a molecule, a microscope, a very cool DNA strand that makes a great arm band, and motifs like the Earth’s layers and a two-toned stegosaurus fossil. We can’t think of a more perfect back-to-school accessory for the STEM-loving kid (or parent) in your house.

As with all of Tattly’s temporary ink, the Science Set designs are safe and non-toxic, and printed with vegetable-based ink. We’d list out the chemical equation for it, but we’re a little behind on our own chemistry these days.

The Science Set of science themed temporary tattoos is available on  for $15 and made in the planet of Brooklyn, shipping worldwide. For more STEM coolness for kids, check out Cool Mom Tech’s review of Amazon’s new original series, Annedroids, about the adventures of girl scientist.
