I used to do this at restaurants when I was a kid.

I was such a little prick.

I didn't know. I just hoped this was real and there was a scientific explanation behind it.

Yes but it was lacking the "hoped it was real" part.

The substance appears to be a rather fluent liquid. But in actuality, it's a viscous colloid of aqueous KMnO4 (potassium permanganate). The gel-like dispersion of this ionic solid throughout the water exponentially increases the water's cohesion (the H2O molecules stick to each other like a solid while remaining in the liquid state). Look up colligative properties.

The "firmer" substance retains the shape of the glass because the structure wants to minimize its free energy. It's easier for it to stay in shape than to settle out due to the water's cohesion. However, a slight disturbance will cause it to change state and *snap* it settles.

So in this case is the glass internally coated with the substance or is it mixed in with the water?
