Destroy the object above you.

[53miner53]

I use a hammer to fix the broken law of motion. (2 out of 2 Apollo 12 moon walking astronauts agree it is the universal tool!)

[cubinator]

I melt the hammer in a blast furnace.

[MaverickSawyer]

I use a backhoe to dig into the fuel line for the blast furnace. No fuel, no fire, and the poor hammer survives.

[53miner53]

I put RP-1 in the backhoe. It explodes. Oops.

[MaverickSawyer]

RP-1 is ignited by the flaming debris of the backhoe.

[Joseph Kerman]

I destroy RP-1 with a fire.

[NSEP]

I destroy fire with water.

[Shadow Wolf56]

I destroy water with heat (and turn it into steam! XD)

[53miner53]

I destroy heat with a snowball earth.

[MaverickSawyer]

I destroy snowball earth with a little global warming.

[Benjamin Kerman]

I destroy atmosphere with blow dryers and blow it into the sun.

[53miner53]

I destroy blow dryers by them overheating due to the excessive work they would have to do

[max_creative]

I destroy overheating with liquid helium. 

[53miner53]

I destroy liquid helium with room temperature and some balloons.

[Speeding Mullet]

I destroy balloons with a pin.

SM

[53miner53]

I destroy the pin with a RS-25 engine exaust.

[Joseph Kerman]

I destroy RS-25 engines with exploding due to excessive hydrogen. 

[0111narwhalz]

I destroy your excessive hydrogen with much, much more excessive hydrogen. So much more excessive that it begins to fuse, transmuting hydrogen to helium and so on.

[TotallyNotHuman]

Your helium eventually fuses into iron. I destroy your iron by melting it down.

I burn it. Don't belive me? Everything burns, if you heat it up enough >:) 

[JadeOfMaar]

I destroy @Benjamin Kerman with the molten Iron a.k.a. attack his life points directly! as he fails to explicitly declare a separate object with which he destroys it so I must assume that he himself is the next 'object' in the sequence in this thread.

Spoiler

The molten iron remains afterward so the next person targets it, not me.

I destroy molten iron with @Benjamin Kerman.

[0111narwhalz]

I destroy @Benjamin Kerman with a kiloton R-bomb at .999999c.
