EMPTY POUCH
You drop the pouch, and the flap pops open releasing the spheres which start rolling around the floor.
The glass spheres start disappearing rapidly under every available object, and down every dinky crack.
The last few glass spheres roll away into inaccessible places, and completely disappear.

LIFT CUBE
You manage to lift the edge of the cube just enough to allow one of the tiny obsidian spheres to slide underneath. Quickly you shove the cube up onto the smooth spheres, and before long it is sliding easily across the floor.

PUSH CUBE
You give the box a mighty shove, and it shoots out of the balcony doorway. Still rolling on the obsidian spheres, it flies into the rim of the balcony, teeter for a moment on the edge, then shoots off!
