I can't break things with the hose in my hand. No animation happens, and grass and whatnot just disappear in front of my eyes; can't break leaves -I can see the "cracks" but when they reach the borders they retract and start again- or anything else. Don't know if that's intentional, tho; I can however assume that grass and whatnot shouldn't just disappear if I try to break it.
I can "use" items (e.g. close a door or open a chest), but again the hose will not animate to show you so.

The hose is not supposed to let you break blocks, because at first I tried to make it Spill/Suck with left and right mouse buttons. It's leftover code, silly, silly, me.
