Whats the most effective way to melt/burn/ whatever, objects so that theres no trace of them left?

Question

No im not a killer...maybe. Whats the best way to completely destroy all materials? My friend and i were discussing it and i think acid is the most effective and he says lava would be best. But doesnt lava still leave traces of what it consumes? Then again, not all acid can destroy metals in a short period of time. Please, educate me.

Answer 1

In a purely technical sense, burning, melting and "whatever" will always leave a residue.

You can't destroy the atoms (short of a nuclear event) - they have to go somewhere and that somewhere can, usually, be traced.

Sorry, not even "maybe" killers can avoid the consequences of chemistry and physics.

Answer 2

Well both are correct...

First try to dissolve the material in the acid, them burn it, then make it into powder and flush out in sink...

Answer 3

You can't destroy matter, you can only change it.

I think vaporization would be the way to go.

Need lots of heat.

Perhaps you could drop object into vat of molten steel in a steel plant, that gets darned hot.  And there's more of them around than volcanoes.

Dropping a thermonuclear bomb on something would leave no trace either.
