Pistons can push many things. For example; mobs. Building a mob farm often requires a lot of pushing, and therefore pistons. Another example; yourself. Some really smart people invented fancy devices that push themselves, and can even push the player with them, but these wouldn't exist without the pushing of pistons. There are many more things pistons can push. Let's hope the pistons in this auction can also push my rupee balance very far... ...
