You can't.

Why did it bend so much ?

Because you wet it. And on just one side from the looks of it. The
wet side expanded. Expanded = wider. Wider on one side = warp.

I wetted both sides, probably more on one side than the other.
..I flipped it over so the good side rests on the floor, This morning
it was almost straight. 3 corners flat on the floor and the fourth one
sticking up 3/4 of an inch. I placed the weights over the table again
and I see tonight what happens.
The board is relatively dry now.. maybe a few days to dry again..?
