An exciting new mod, the Minecraft piston mod adds moving, working pistons to the game. They’re not Steampunk pretty (yet) but they work. How do they work? Well pretty much as one might expect them to. They lift and push using the power of steam, or in the case of Minecraft, redstone. Especially useful is the fact that pistons operate on both the horizontal and vertical planes. They can also act as launchers. If you place a block like sand above the piston, it will be hurled into the air when the piston is activated. Fun and games for all the family!
