Redstone Flying Machine (Minecraft)

You're going to need to kill a lot of creepers...

1 Sticky Piston

1 Piston

5 Slime Blocks

3 Observers

1 Dispenser

192 (or more if wanted) TNT

Just as an FYI: I don't take pictures of each individual step in the game, I draw them out on a drawing software.

You need to add a slime block to the right of the dispenser if looking at it from the left side.

Put 3 or more stacks of 64 TNT into the dispenser for mass-destruction!
