Super hard one, we ended up peeping through one set of portals to shoot the funnel where it needs to go to save the ball but you could easily add a pane of glass to block this.

there u go. under 2 hours, yay :D https://www.youtube.com/watch?v=1lF9taPgT7s

Love the great small chamber puzzles like this. a lot of difficulty in a small room

Looking forward to Confinement 20. When you get a chance could you try out my chamber Asylum and let me know what you think. http://cs2bus.com/sharedfiles/filedetails/?id=154441170

Thanks for finding that! It's fixed now. Also, I plan on making 20 soon. It will probably be the last one in the series, so it needs to be extra hard. :D

Camerson this chamber is exploitable all you have to do is get the cube and set in on the button at the begining and then go in between the 2 lasers and have partner destroy the cube thats how we solved this one. Also only other way i could solve it was me and my partner outside the confinement which the spear is pointless at that point cause the exit is not locked but we wanted to see what the spear did anyway, so we did go get it. but very exploitable have to rething that one loved your other chambers though.
