Orange, or the player with the funnel, needs to jump across the platforms to the other side. Move the funnel around until the platforms are covered in gel. The goal is to splash gel on the two platforms down below. Blue places the second portal on the side wall and then releases the gel. Orange places a portal at the end of the funnel and then on one of the platforms down below. Blue will need to stay here to release the gel.
Press the red button to release the gel and then Orange can bounce off the gel onto the ledge. Place a portal under the gel dispenser and the other on the sloped panel near the roof. Place the second portal so Blue can come through as well and go through the exit. Use the gel to jump up to the next platform. Orange drops down and gets back onto the first ledge. Raise the platform so Orange can reach the ledge to push the next button which releases more gel. Blue steps on the red button to lower the platform while Orange jumps from the gel onto the platform. Place portals to get up onto the ledge and press the button to release the gel. Blue gel helps you to bounce and orange gel makes you run faster. This level introduces Mobility Gel which can be used to jump higher or run faster.
