you gotsto use teh pivotted slab in teh water to catapult teh 2 cages up onto the raised bit where the pressure switches are. you can drag both teh cages onto the lowered end of teh pivot, then go up to the raised bit and jump onto the high end of teh pivot, and it launches em up to same level as teh switches.. then you just move em into place.. and teh door opens.. then do some climbing and swinging and thats teh end of teh demo
