This is my first Trap with pistons.
The Cows Spawn and fall into the water.
If A cow drops sth the pistons close the way so that the cows "wait" to you collect the item.
The pistons open again and burn all the cows.
Godd Cance to cook the Beef.
Not finished yet work on a air cow piston trap much bigger.

Sorry for the bad Langue i am German and write english that everybody understand.
