Light In The Show! by Marcono1234 by mcpillager12

Copied from Marcono1234's post:

Marcono1234 humble-lee(!) presents. Light in the Show! This needs redstone. Not always active.

So the contraption.

Step one. Build something called redstone repeater clock.

Step two. Place repeating command block (needs redstone, not always active!) with the following command inside of it. '/summon Chicken ~ ~1 ~ {CustomName:Light in the Show!,CustomNameVisible:1,EggLayTime:9,Passengers:[{id:FallingSand,CustomName:Light,Block:structure_block,Time:1}]}'.

Step three (last step!). Go near those chickens and collect their eggs. For free. Very very free. That is it.
