TNT Launcher is used to launch TNT in the air. You can make it explode on the ground or in air.
Go through this guide and follow step-by-step instructions to make TNT Launcher.
The first thing you have to do is to place 15 smooth quartz blocks on the ground in the same way as shown in the image below.
Place a smooth quartz slab at the bottom area and fill the gap with water.
Place 3 TNT at the top of the water and one at the top of a smooth quartz slab as shown in the image below.
The next thing you need to do is to place a stone button on the smooth quartz block and add a redstone repeater on the ground.
After this, you have to place eight redstone repeaters on the ground in the same way as shown in the following image. Set all the repeaters to maximum delay.
Now you just have to press the stone button to activate TNT launcher. It will launch the TNT in the air.
