The Portal Chamber will be located inside Row 4 Floor 2.
This idea will most likely be one of the most complex crushers to code/make.
This crusher will start with a conveyor belt, entering a room with 2 pairs of portals, one for the ceiling-floor and another for the right-left walls.
You will move your car inside the chamber, and then go into the control room to put the crusher into effect.
You can do this by opening the floor-pair of portals, this will make the car fly down endlessly at increasing speed until it reaches terminal velocity, you can obliterate the car by closing the floor-portal, sending parts everywhere. You can also close the floor-ceiling portal and open up the wall-portals, sending the car flying into the wall at its falling velocity.
Pretend like giant vehicles can fit through the portals/entrance
The controls include, conveyor, open portal, close portal, close portal pair, open portal pair.
