INSTRUCTIONS:

Controls:

The lever "Lever 1" farthest left on the dashboard is attached to a piston that drops creepers into a pit for easy riddance of test subjects.

The lever next to it "Lever 2" summons lightning to the chamber.

The button next to that lever "Button 1" summons a Creeper into the chamber.

The button next to that button "Button 2" opens a piston "gate" that allows water to flow into the chamber, extinguishing the fire that the lightning causes.

USAGE:

Hit "Button 1" to summon a creeper into the chamber.

Hit "Lever 2" to summon lightning, which supercharges the Creeper.

Hit "Button 2" to extinguish the flames so the Creeper doesn't die due to the fire.

Hit "Lever 1" to drop creeper into a pit of Lava, allowing for a repeating of the process.


Even with a rudimentary understanding of Redstone tech you can even turn this into a killing chamber. (Death by lightning, drowning, etc.)
