Yeti Rambler Tumbler Coolers 30 OZ How to Test the temperature?You can use a thermometer to test the temperature of the liquid. Taking a temperature reading every minute for at least ten minutes, then again around 20 minutes and 30 minutes, will help to show whether the paper Yeti Rambler Tumbler is indeed the best insulator. You can record these readings as a graph if you wish to make the results clearer.

Heat retention:In an extremely similar test, Yeti Rambler Tumbler and food container specialist Contexpan discovered that the liquid in both Yeti Rambler Tumblers dropped in temperature very fast during the first five minutes, from around 100 degrees centigrade to around 90 degrees. Yeti Rambler Tumbler Coolers 30 OZ However, at this point, the liquid in the polystyrene Yeti Rambler Tumbler cooled at a slightly slower rate than the paper version, remaining at around 80 degrees after 25 minutes compared with the liquid in the paper Yeti Rambler Tumbler, which had dropped to around 70 degrees.The findings suggest that the polystyrene Yeti Rambler Tumbler is the better insulator, with the paper Yeti Rambler Tumbler in second place.

A third Yeti Rambler Tumbler, a plastic Yeti Rambler Tumbler, was used in the Contexpan test and this presenting inferior insulation properties, with the water temperature falling to below 70 degrees centigrade after 25 minutes.

Further tests would need to be carried out to discover whether this gives the paper Yeti Rambler Tumblers the edge over polystyrene ones.From the findings above, we would most likely expect the greatly increased insulation of ripple/weave paper Yeti Rambler Tumblers to put them in first place with this sort of experiment.The ripples act like a thermos flask, greatly increasing the heat retention of the Yeti Rambler Tumblers.
