The idea wasn't to simulate the sleeping pad, but to demonstrate that ice and snow absorb heat a lot faster than granite. Try the ice and rock experiment. You may be surprised. About 1 oz of each in 4 oz of water
But that aside, the test with the neoprene glove will demonstrate the same principle, regardless of the ambient temp. The ice cube will feel colder, sooner, than a much colder rock of equal mass. And the rock will warm up to a comfortable temp before the ice melts,
