The live crab vending machines on the Chinese subway will save you a trip to the grocery store. The food dispenser contains live crabs that are kept in a hibernation state and packaged in custom plastic containers.
One person who tried the crabs from the machine said, "Two days ago, I was passing by, and saw that they were cheaper than at the markets. I was curious, so I got two. They tasted all right, so I'm back today for more." For another wacky protein vending machine, check out this meat vending machine.
