Once they are in, the player controlling the funnel will need to make a portal in the center wall so that when the other player presses the button in the office, a lens cube will fall and land in the funnel.
Once it does, the other player can hop in the funnel to grab the cube and repeat the steps necessary to get them back up into the office.Once the other player is back in the office, they need to set a portal on the far wall and direct the laser through the portal. The player who is controlling the funnel then needs to set up the portals the way they were originally to bring the other player over to where they are.
