|“||These walls look weak. But maybe it's because I've been working out. I'm so firm and well-toned. 35 minutes of cardio then upper torso and abs. It's really hot in here. Especially down that way. Good thing there aren't any explosives nearby.||”|

Upper Shaft is a level in the video game World of Goo. It is the fourth level of Chapter 3. The player needs to lower the encased Bomb low enough for it to touch the walls, light the fuse to explode the Bomb and open up the walls. Finally, the player must extend a structure to the pipe located across the shaft while avoiding spikes and blades.
Due to lack of Water Goos and the fact that the Bomb case is already attached to the hanging structure, an alternative method of lowering it must be used in this level to extend the structure by using Green Goos.
