Free to print posters from NASA’s JPL are beautiful (and awesome)!

From JPL, NASA. The below is my favourite one (although the artist’s name isn’t on the document – anyone know who it is?)

Also some back story to the “Grand Tour” idea here.

OK. This is cool: crayons named after specific chemical compounds and the colours they make.

From their Etsy site:

“Children play and draw with crayons practically every day, so why not make the experience more educational? This listing is for a set of 24 labels to stick in the crayons in a basic 24 pack of crayons so that while children are coloring, they are also exposed to the names of chemicals that will make those colors! So instead of thinking “I want green” they will think “I want Barium Nitrate Ba(NO3)2 Flame” and then when they take chemistry in high school and their teacher sets some gas on fire and it makes a green color and they ask the class what chemical it was your student will know it was Barium! Genius!”
