These tiny terrariums seem kinda cool.
Unfortunately, given our prior history of plant keeping, they’d die from dehydration. Or get knocked over and die. Or get hit by a tiny meteor, but survive, only to contract a newly arrived viral infection propagated through interstellar space by comet. And die.
Actually, Nicola has just reminded me about her bonsai, which survived all of 3 days. It died because it was accidentally left in the window in full sun while she had gone out to the library to get a book on how to look after her bonsai. :)))
