The frosh class pranked the last physics 1a lecture by opening some portals in the middle of class.

First, a frosh waked in and shot a portal gun to start the prank off.

Once the portals were activated, a series of frosh went in and out the various portals while the “Portal” theme played.

The timing was perfect, and at the end of the prank the class was lectured a bit on some of the physics in the game.
