Insert anything into the vending machine, except money, then sit back and watch what comes out the other end.....you insert the object, someone else tells you what you got. Then that person inserts something. Only one rule!
Person One : I insert a ball of yarn.
Person Two: You get a new scarf.
I insert a loaf of bread.
Another Person: You get croutons.
I insert a tomato plant.... etc, etc
