There's probably enough of an air gap between several sheets of paper towel that the temperature could drop on the top paper towel UNTIL something heavy - like your ball python - lies on them and they get compressed against the bottom of the glass.Originally Posted by MarkS
The temp drops by 30 degrees due to a few sheets of paper toweling? Those must be some amazing paper towels.
Also, OP has said he's not using a digital thermometer or temp gun so he really doesn't know the surface temperature on that top paper towel.
