TNT are meant to blow stuffs up. However, besides that, there are other many uses for TNT that not many Minecraft players know about. Here is TNT Stuff, a Redstone map that introduces a bunch of Redstone creations utilizing the effects of TNT.
TNT Rocket Launcher
With the power of TNT, this contraption can launch you – the player – more than 1200 blocks in the air. That is very much high than the clouds and almost into hyperspace.
This launcher can launch players or mobs forward. You can use it to cross a big gap.
Fire Arrow Fountain
Completely harmless to look at, unless you decide to grab the arrows. This works just like a fountain, but instead of water, you have fire arrows. Arrows will be fire straight up in the air and land on top of hoppers which will retrieve the arrows and shoot them back again.
Warning: May cause burning.
It is not easy to get the best height out of this thing. You need to time the explosion just right.
It is obviously what TNT is made for, blow stuffs up.
So those are some of the cool TNT stuff. Install the TNT Stuff | Redstone Map for MCPE and check out more.
