Minecraft tutorial?

Today I saw a video on yt where a challenge was made, in which if you put an item in the workbench, a surprise product always comes out. I play Minecraft on the computer how can you do that?

Randomizer mods.

Okay, can they be found on Twitch?

No.

First you have to know which mod it was, and then you can search for it.

I have to try it

That was a Spigot Server plugin but hey…
