Yeah, that's it.

Is the intended way to make a portal on the wall above the laser, the other on the floor, and hold the cube through the floor portal and drop it? That's about the only thing I can come up with...without putting gel down there :P

No idea how to get gel on the ceiling...but I'd think of something :) In one of my unrecorded runs I somehow ended up with a blob of gel on the roof...and had to resist using it because I didn't know how I got it up there.

The gel part is fine; I know enough to pick my battles there. I kind of want to just remove every pillar except for the lit ones, but then I would need lifts everywhere. I am curious how you would get terminal velocity with no portal surfaces on the ceiling to start with.

However, you're still doing the reflection cube placement the hard way. I've got one more try to see if it forces you to do it the way I intended.

The laser wasn't very difficult, and the glass hardly a problem, just because I solved it that way doesn't mean it's the easiest solution. Here is my rerun, only 3 minutes and 30 seconds including errors. https://www.dropbox.com/s/1f16v2iq9jqorhh/practiceroom7-2.dem

The lifts are great, they don't compromise the puzzle yet are very helpful. Also the roof is tempting me...if the solution wasn't this easy I'd try to get some gel up there (terminal velocity...) :P

Thanks for the demo. I must be a sucker for punishment because I've got an update. What am I even thinking.

About six minutes including plenty of mistakes https://www.dropbox.com/s/tk9zqzbs42og0wz/practiceroom7.dem without all the mistakes, maybe 3 or less. I haven't tried it but I would think the knight pattern would be slower because of the more precise portal alignment needed. My line only requires straight portals. I may have a look at that map...

@Prototype Just curious, how long did that take you? The main purpose of this map is to teach the "knight" pattern (two out, one over) because I've found that to be the most efficient way to get things done at the end of Seven Layer Nightmare.

That was fairly straightforward, I solved similar to your screenshot (except I coated every second ledge in a straight line). Ended up being fairly repetitive, and I didn't learn any new tricks. Also it was quite tiresome walking back to the start if you don't make one of the jumps. Apart from that it was a nice level, but it could have been shorter.

That's one of the things I don't completely master with gels : spread them precisely, and not randomly everywhere :p

Just dropping my most advanced map about gels here : Moondust ;)

Yeah, in the end I was more cunning about the how-to. But the way to there let me make some tries and failures, as in the beginning I didn't even know how to continue. In the end it was a straight forward and not the crossing.

This takes me about 5-6 minutes, depending on how many times I mess up. A pefect run would probably be about 4.

You've got the right idea, but you can do it with a lot less "painting". This is what it looks like when I'm done . Note that the lights aren't just for decoration. .

Yes, "Gels and Angles" is way more weird, I experienced.
But this one is also really something!
I still wonder, if this is the intended way. But it looks like.
And I am interested in how long you need to go through THIS chamber.

Yeah, the final part of my latest maze is particularly tricky and it would suck to get all that way and then get stumped. This was so much fun that I went back and did the same thing for the other mazes.

If you're looking for even more "practice" then I actually have another old puzzle that does even weirder things with conversion gel:
Gels and Angles

Oookay, getting on the gel is not the problem. I think I have to learn the tricks now...
I think I must be glad, there is now a Practice Room before the 'real thing'!
