Night spa & pool

We have been using our spa a couple nights a week. We can get it up to 101 degrees in about half an hour. It is fun to sit out in the hot spa and look up at the constellations.
Even though the pool is in the low 50s, Geoff, Derek and Katie have been jumping in, quickly jumping out and running back into the spa.
I think they are crazy. Here's Derek listening to the countdown....3, 2, 1 JUMP.
and I snapped just before he hit the water and it looks like he is standing on the water!
