I solved it without making use of the orange funnel. Here's how:
First shoot a portal from center to funnel room. Then put the portal in that room on the funnel and funnel back to the center. Stand on the button in the center room and shoot a portal to the left of the funnel room so that u get a funnel a little higher than on plate high so that u can take that funnel and get to the third room. Get a cube. While standing on the button connect middle room and third room with portals. then go to the middle room and place the cube and go back to third room. Place the portal so that it is as far from the wall as the cube on the button on the middle room is. Stand on the button in the third room and shoot the other portal to the funnel room. Go to the funnel room. Now use the funnel to destroy the cube in the middle room and quickly shoot the funnel so it pushes the new cube onto the button in the third room.

Came back to this one again, but I’m still not sure if I did it as intended; what I did was from here shoot portal behind me, re-spawn cube and place on button like this go through portals to here shoot portal here so cube is pushed to fizzler and auto re-spawns then shoot portal here so cube is pushed onto wall button to open exit - intended?

Hey Rector ! As Polux I didn't use the orange funnel, using regular moves only. My solution is logical and satisfying though !

Nice puzzle. On the cube dropper area, i jumper on the pedestal button to get to the orange funnel, is that intended?

"tae" = 'take'! letters J, K & L don't work sometimes.... time for a new keyboard

Really good puzzle, but I don't think I did it by the intended method as I didn't use the reverse funnel. Looked at LB's play through and I didn't do it that way either. I'll redo and tae screenshot + explanation if you like, unless you are going to update anyway?

I didn't cry, did I do it wrong? https://youtu.be/K0LUoN7Hjoo

Nice puzzle, was pretty straight-forward to me but still enjoyed it! Thanks!

Nice one, well done.

Nice work!

Remove the white blocks from the white wall. They're unfairly unrecognisable and can cause frustration. if you don't want the player to place portals there, replace them with light strips.

Other than that the test is pretty cool.

Yeah, duly noted the trapping issue :P hope this will get fixed soon. Puzzle looks good though (as always)

Solved again, in what I can only assume is the intended way. I liked the grate making sacrificing the cube at the end more difficult than originally, even though this grate is responsible for trapping the player.

I haven't solved the new version of the puzzle yet, but I'd like to point out it's now possible to get stuck on the Funnel side of the map if the fizzler is up and you have both portals on that side.

Guys, I'm pretty sure your solutions are unintended since you never used the reverse funnel. I updated it so I think you should be able to find the intended solution now. One issue: It's possible to trap yourself if you're in the funnel area and you shoot both portals on the wall there. Remember not to do that.

@TheWinrar No, it has a use in the puzzle. :P

@Innocentive Thanks for the video! Your solution is the same as Polux's since you never used the reverse funnel, which is unintended. :(

I did what Polux did....

took me a while before i realized how simple the solution was

I'm not the map creator, but at

@Polux

I'm pretty sure that was the intended solution, and the funnel reverses to prevent you from solving the puzzle an unintended way.

You had me there for a couple of minutes ... was much easier in the end than I originally thought. Here's my blind run .

I never used the reverse funnel ...
I just 'killed' the cube in the goo, with the funnel in front of the button.
