They say that form follows function. So - take a look at the form of this strange device, which stands about a meter tall. Can you guess its function?
No, it isn’t a trashcan with dreadlocks.
I saw this thing in the Biosphere at Potsdam. This pleasant museum is smaller and less ambitious (should I say, less pretentious?) than the one in Arizona, and serves very well to exhibit different ecosystems to the visiting public.
The item you see here is a display device for displaying smells. You sniff the end of a tube to get a whiff of the plant shown on the round image below it.
Did you guess?…
