1. Place a piston (or sticky piston) with its direction heading to sky.
2. Place any block above the piston (above the wooden part)
3. Place a redstone block abobe the block you placed in 2.
4. Destroy the block in the middle.

If you do this in Minecraft (PC), the piston will move.
However, the piston won't move in PE.
Plz fix this bug! x(
