A Cobweb

Cobwebs are blocks that slow down movement, and are only able to be collected with shears that have the Silk Touch enchantment. When harvested with normal shears, they drop as string.


Cobwebs slow down mobs, and if you can lure mobs into the Cobweb, you can easily kill them. 


- Can be used as the door of a mob-protected room, since minecarts can get through with ease; mobs can't.

- Items thrown at the cobweb will slow down

- Sand falling will slow down, then break. 

- The slowest speed in Minecraft is: Placing ice under soul sand, cobwebs above the soul sand, then, walk in backwards blocking with your sword, sneaking, and under the effect of slowness
