You need to be on creative to do this. You need bricks, TNT, sticy piston and a lever. First make a cross 3 above the ground and 1 on each side.Then hit out the middle put about 4 more bricks on each brick still there then get on top and brake 2 of the bricks at the end then put a brick on the 3rd in side then go to the back an fill in the rest from the to the last brick.Then take your sticky piston and put it on the second brick you have opean then put the TNT on your last one cover the TNT and sticky piston with your bricks then what ever side the sticky piston put the lever put the lever on the left or right side then swich the lever then BOOM!! P.s. does work in rain p.p.s. if dosent work put the swich by the TNT then flick it.
