Looks siliconey. But also wormy. How big is it?

Any pets that could've dropped *whatever* in there? Roommates? Was it actually floating at the top?

If it actually did come out the tap with the water, my guess is some sort of flocculant/coagulant used in tap-water treatment, that somehow made it past the system and was still dissolved/in suspension in the water. Then settled out during the night.

These chemicals are used to attract particle in the water and clump them together for easier removal. Some of those "concoctions" looks similar to this after settling out.

Edit: If you put it back in a cup of water that just came from the tap, does it dissolve? If so, it can be something that's solvable in chlorine (or chloramine, depends on what the plant is using), but not water. Might help narrow it down.
