The movie 9 wasn't that great, but it's animation was. The story had promise, however.
I built a thermal test chamber years ago that circulates cold air around a test subject with air fans. Dry ice is loaded into a metal in basket and then two smaller in baskets sit on top of the dry ice. The experiment sits on top the stacked baskets allowing cold air to flow around the experiment.
Right now the Popular Mechanics near space tracker is inside. I plan to let it chill for 30 minutes (at least) and compre the internal temperature of the reusable lunch sack to the outside air temperature. The dataloggers for this test are Hobos.
