That block under the chest. Is that a dispenser? Or a piston? Is it some sort of remote BUD switch?
I demand answers to this mystery!

I have discovered a truly remarkable proof of this, which this margin is too small to contain.

It took me like 10 min to figure out why the comparator.

I'll answer anyway, for people who don't know. A comparator constantly updates the blocks in front of it. This allows you to create an easy instant bud switch.
