There are even mail order services which will send you a pretty box with a pre inoculated block in it. Open the packaging, keep it under your table and check it so often, and you get tons of mushrooms. It's really fun. The utility of this device is extremely questionable, but I can't deny that it's really pretty and a good conversation starter.
