I'm pretty sure the water would circle the sink drain the other direction.

Strobe-like....far out man. Total strobe-out. Like old silent movies.

In all seriousness, It's only 85 minutes to orbit in LEO, so if the Earth spun this fast it would probably be outside it's Roche limit and fly apart.

Spinning that fast, I'm sure Guam would flip over.

In all seriousness, It's only 85 minutes to orbit in LEO, so if the Earth spun this fast it would probably be outside it's Roche limit and fly apart.

So, something like this?

Would not matter to me.

I suspect if it span that fast then the relatively weak forces of gravity would be largely or entirely negated by the centrifugal force. I'm sure someone knows the answer to this. What is it?

It's centripetal force (acceleration), and at a 2 hour rotational period we would feel pretty light at the equator....
At the equator, a rotational period of 1 hour and 24 minutes would provide centripetal acceleration that would equal the gravitational acceleration - ie. one would be virtually weightless.

The question though, is how much would the earth oblate, and would the "new" equator be outside the area where centripetal force exceeds the force of gravity... It probably would
