Fruity Chimp Goes Green

Meet Pavlov's chimp, who probably can recycle better than you.

Here's the drill. Miru, a five-year-old primate at the Tama Zoological Park in Tokyo, likes fruit juice. She's learned how to deposit money in a juice machine, drink up, deposit the can, which triggers another coin that allows the chip to drink another can of juice.

The chimps are allowed to drink til they explode.
