Terraria? You decide. Then you pick a 2-1/2” tall plastic egg-shaped terrarium filled with “sprouting mixture” and the seeds for either a eucalyptus plant, an asparagus fern or an insect-eating hooded pitcher plant. Each sprouts in a week or two on a southern or eastern-facing windowsill and then can be moved into a larger terrarium, we’re assured.

Volcanologists call these popcorn hyalite bombs because they're globs of molten lava that were spit out of vents on a volcanic cinder cone, flew through the air expanding (like popcorn), and came to rest as glass-rich pieces of hyalite. These are from Echo Mountain in the Medicine Lake Highlands of northern California, and yours will be approx 3-1/2" dia, give or take, since volcanoes won't spit to order.

Let them paint in 3-D with these little raised-plastic reliefs of a dinosaur (either a T-Rex, stegosaurus or triceratops, our choice) or an insect (either a butterfly, dragonfly or bee, our choice). All are 4-1/2" x 2-3/4" and you get (4) little paint pots in yellow, red, blue and black, a basic brush, and a cardboard easel for display. Artistic bonus: the reliefs have a velvet-ish texture, so the result resembles a velvet Elvis, if Elvis had been an insect or a dinosaur.
