Is there a way to "stick" blocks?
Can someone "stick" blocks in Minecraft? I mean that if you push one with a piston, will it be possibly pushed together with other blocks?
Solution 1:
Yes, the item you are looking for is the Slime Block, added in version 1.8.
The slime block is a block, made from 9 slimeballs. When pushed or pulled by a piston, it will drag all adjacent blocks with it (up to the usual maximum of 12). Using multiple pistons, it is possible to build vehicles.
