Ever wanted to get a good view of the land around you in Minecraft? Well, a player launcher is GREAT for this! See the widened platform of bedrock? That's how high I got launched with this design!
Step 1: Gather Materials
You will need:
°97 (1 stack of 64+34) stone, cobblestone, ect. I am using bedrock because I am in creative mode.
°1 lever or button
°17 water buckets
Step 2: The Box
Build a 7×7 platform out of stone, building the outer ring 2 more blocks high. The stone in the picture is to reference the dimensions.
Step 3: Add the TNT
Put the TNT in the center, in the formation you would use to make a chest or furnace in the crafting table, one block away from each side.
Step 4: Add the Water
On the same layer as the TNT, put water on all the rest of the blocks, like in the picture.
Step 5: Redstone
Put redstone on all the TNT, exept one. The one without the redstone is where the lever goes.
Step 6: Fly!
Stand in the water in the middle of the TNT, flip the lever, and FLY!!!!!!!! (If you are if survival mode, try to land in the water so you do not die of fall damage.)
