Hi everyone !
Here's a glitch-map that present a trick i discovered by chance.
Maybe it was discovered before me, but i'd never heard about.
I tried to adapt so i wrote instructions in english too, but as french is my main language, it might be a little incorrect.
But plz, be nice :)
Also it's short so don't worry of wasting your time.

In summary, it's a glitch that permits using a piston without using redstone.
It can be cool in gamemode survival, if you have not enough redstone.
Me and my friends can't explain why this happens - probably a code error - so let me your ideas in the comment section.

Also I will publish a new map VERY soon, (as this is a short map) so consider subscribing.
It will be a parkour/puzzle map.

Hope you enjoy
:)
