Insulative Quality of Tumblers

Parker Moreland, Danbury, CT, has come up with many clever uses of our products over the years. This time, he performed a simple experiment using Logger Pro, LabPro, and four temperature probes. It is a study of how well various insulated tumblers keep a liquid warm. The best was an expensive, vacuum tumbler, followed by an inexpensive, polystyrene double-walled tumbler, then a polypropylene double-walled mug, and finally a thin, glass tumbler. Eight ounces of hot water was poured into each tumbler and a temperature sensor was placed in each. Parker says a surprise was that the double-walled tumblers and mugs that are so popular now are only a little better than glass.
