Old and busted: Tamagochi's, new hotness: homemade biospheres.

I'd like to make one with a tiny crawfish inside.

I have always been fascinated by the smooth glass orbs sold in Hammacher Schlammacher and similar catalogs, and it turns out you can make your own very easily. My friend Rand had one... he also had a Galileo thermometer I was jealous of. Now I can outdo him with a whole family of homemade Biospheri.

Thanks Make:!
