How to make "trick" stairs in Minecraft (video)

[ElizabethAlison]

I'm sorry if it's really laggy. This computer isn't that good with recording and playing at the same time, so yeah. :P
Explanation:
The piston pushes a stone block up, and above the stone block are two sand blocks. Among all the blocks in Minecraft, the sand and gravel blocks are the only two gravity-obeying blocks. Since the sticky piston only pulls one block back even though it pushes 3 up, the other two blocks must fall by their own means. Once the pressure plate is stepped off of, the piston is released and pulls the stone block back, and the two sand blocks follow.
