A redstone wave is absolutely useless but it’s really eye-pleasing to look at. It’s like an installation of art using minecarts, pistons and redstone. There’s really no size limit but this particular one is big enough to creating a long lasting impression.
Press the stone button found on one of the blue wool blocks. Once it’s pressed a redstone signal will be triggered and soon after the redstone wave will begin.
The minecarts will be launched up into the air and cause something looking like a wave but eventually it will stop. It’s quite useless but definitely cool to look at!
We recorded a short video to demonstrate how this looks like in-game!
Here is the video by Adventure Gaming HQ which originally created this fun invention in Minecraft Pocket Edition.
