Took a regular/ clear water bottle, insulated Polar bottle, and insulated Camelbak Chill and Ice. Seltzer Bottles will be included in the next test when it gets warmer.
Put in Southern facing window--but sun didn't come out all day. Inside temperature 64-67 degrees. Froze the bottles and left them out for 9 hours--plan to measure ice remaining in the bottle.

After 9 hours strained out liquid and some ice remained. In the clear bottle two little pieces of ice remained, in the insulated bottle sausage sized blocks.

Dr. J. Clear Plastic Bottle--ice remaining in bottle, 7 grams (1% of liquid)

Camelbak Chill-ice remaining, 173g (31%)
Camelbak Ice-ice remaining, 217g (40%)

While testing, 2 weeks late (rained out on New Years Day), Jack, Dr. Dave and I climbed Mt. Diablo. Until @1250' couldn't see 10 feet in front as dense fog. Then it got sunny and very very warm--partially very warm as we were all bundled up. My wool tee-shirt dripping wet at the top.

Lots of "tourists" (Dr Dave's word) on Mt. Diablo. On the summit ramp 2 pickups and a 3 wheeler blocking the road while debating who was going to go first. In the start of the Muir de Ward a minivan in neutral square in the middle of the road. And going downhill from the Junction a cyclist in the twilight zone cut across the road and cut Jack off..
We came out of the
