The Very Jeweled Rattuses

They learn how atoms, like friends, stick together to make the growth patterns we can see in the crystals, and they also learn how common things in the home, like salt and sugar, are crystals which you can grow!

Crystals are magical, but not in the way some new-age retailers would have gullible shoppers believe. The Little Rattuses™ find beauty and science in these wonderful objects, and share their ratty observations on the world as ever in this, their tenth outing.
