Dose any one know who Joshua Klein is. I do. He is a smart man. He does research on crows. He is trying to train crows by showing crows how to use a vending machine. There were for stages to the vending machine. He got the idea form a cocktail party at he's Friends house he's friends wanted to kill them. But Josh wanted to help them and now we will go throw the stages

Stage One
There was the vending machine in Field's with nuts and coins all around it. The crows came along and see the nuts, coins and this machine. They come along and eat the nut whenever they want.

Stage Two
The crows are use to the machine and the sound and so crows can came and get a peanut

Stage Three
When the crow's came back for a peanut but there is only a coin. They try playing with it and Finlay one of the crow's but the coin in then they learn how to do it.

Stage four
The crow's show up and nothing happens but when they see the coin on the ground they put it in and it work's and it goes on for same time until there is no more peanuts left
