Experiment #6: Light Bridge Deflection

Thanks.

By dropping it in the goo. There's a walkthrough video here: http://www.youtube.com/watch?v=pc-R6U9AH_U

But how am I suppossed to destroy it?

That's actually part of the puzzle. If you destroy the companion cube, a clean one spawns and bounces up the gel-covered walls for you to collect. :D

Ah. Thanks.
Also, on the map with the companion cube and repulsion gel, the cube gets covered in repulsion gel and thus it keeps bouncing everywhere, making you unable to put it in the button. Do you think you could add a small cube-washing station (a space big enough to fit a cube that drops water on it from above) to the room?

I think you might be approaching the puzzle in a way I didn't intend. The intended solution is to slide across the angled light bridge before hitting the far wall; there is no traveling through portals.

But aside from that, it is a cool map. Sorry for getting mad earlier.

While it is a cool concept, there is nowhere near enough time for me to make the jump. Not only that, but everytime I place a portal on the tilted platform, it moves to the middle instead of the side.
And of course, I always get stuck in the portal whenever I DO successfully make the jump.
