if you leave the top open so the water can expand, won't that work ok?

You'd think so, but I left a watering can filled with water on my porch.
It
froze solid and the ice pushed the bottom of the metal can into a round
shape. Very weird. Half the top of the can is wide open - plenty of room
for
expansion.
If the ground was warmer than the air then it probably froze from the
top and sides down towards the ground, creating a nice plug that
apparently was stronger than the bottom of the can.
That makes sense. It was on a cement porch where snow still melts when it
lands - the cement hasn't totally cooled down yet.
