This is irresistible! I shall go and carry out exactly this experiment immediately! Watch this space...
Of course, glaciers are moving, sliding along the bedrock. Sometimes there is liquid water
under them. (Not frozen to the cup)
A glacier is hardly one big piece of solid ice anyway. Anyone foolish enough to think so would be down a crevasse soon enough.
But IF glaciers were frozen down..
I did rough calculations-you could see what you comee up with- to see what sort of
buoyancy you'd get from a mile, two miles, five miles of ice. How much lift per square
foot. How many tons.
A mere
girl, no more than say, five ft tall, could break an ice cube free, bare handed.
How many tons per square foot is this ice-glue to withstand? Do calculate it. Not that it is frozen down anyway.
Maybehe'd hear it from a fellow believer. A awful asian atheist
, not so much.
For a visual, here is some floating ice. No five miles thick, but that is a lot of ice
lifted pretty high, Five miles of ice would have what, about 2,500 feet above water.

I wonder how confident our hero of the ice cube in a bowl would be, if we took
a column of 2500 ft of ice, froze one end to a high ceiling, and let him stand under it when we removed the supports. Is that ice gonna stay stuck, or is one world trade center atop another
with Washington monument on top worth of ice gonna break free and bonk him?
