How cold does it have to be for water to freeze before it hits the ground when thrown outside?

when I was growing up in Northern British Columbia I can remember me throwing out dishwater and it would be icicles before it fell to the snow. Is that cold or what?

How could the LEM leave the moon but no fuel tank and then accelerate to a speed of 3000 mph to the orbiter?

We did not have the technology in 1968 to accomplish a moon landing. Looking at pictures of the LEM makes me feel that we were so naive at the time. I downloaded all NASA schematics and guess what... no fuel. So how the hell did we get back.
