Course 2 - Mass and Velocity

Course 2 - Mass and Velocity

Test Chamber 3

Player 1: Like in the last test chamber, this is all about using the speed generated by an 'infinite loop' of portals. So set your entrance portal and exit portal on the horizontal panels in the upper corner.  Once player 2 is gaining terminal velocity, walk to your left and look up in the top right-hand corner by the wall. There's a vertical wall panel up here that you need to fire your EXIT portal on, causing player 2 to travel all the way over to the other side (across the chasm).

Player 2 : Wait for player 1 to stand on the red switch near them (raising the platforms over the pit) and then once it’s safe to do so, press the red button to release the round weight.

Player 1: Wait until player 2 has crossed the bridge fully before stepping off the red switch. Now get a portal on the nearby wall and one up on the wall leading near the entrance/exit.  Both of you should step through and the weight needs to be dropped in it's appropriate place to open up the exit.
