A
fun thing to do in extreme cold is to throw hot water into the air. Take a
flask and fill it with boiling water to warm it up, pour this away and
fill it again. Take the full flask outside, take a cup of this hot water
and throw it all up into the air. As the +100°C
water meets the cold (in this case -32°C) air, it instantly vapourizes.
Most of it is turned into a cloud of steam that drifts gently away and
some of the droplets that stay together are instantly turned into small
pieces of ice that can be seen streaking down towards the bottom left in
this photograph.
It's
very weird to throw water into the air but none of it ever actually
landing. Also seen in this picture is a solar halo around the sun formed
by the ice crystals in the air.
Note - this only happens with very hot
water - cold water just lands as cold water. There's a video
here from Canada.
