Portal 2's numerous brain-bending test chambers are enough to confuse me even with the use of the game's titular portal technology. Actually solving one of them without using any portals? Unfathomable.

Nonetheless, that's what YouTube user lost4468yt did in chamber 20, one of the tests that involves the use of laser-reflecting boxes. Watch his insane accomplishment below and weep that you'll probably never do something this ridiculous. Or just keep enjoying Portal 2 the way it's meant to be played.
