Our father differentiate us that the best way to test whether a steaming loving cup of anything was cool enough to drink was to just drink it . It was n’t until the fifth clock time we were in the hospital that we discovered that the man was n’t our father . If we had these hotness - sensitive On / Off mugs , which exchange from the Off billet when nerveless to the On situation when hot , we ’d still have our original clapper . However , as Joel from BBG points out , the heat - sensitive plastic facing has a inclination to wash off — direct to a scenario where a pragmatic jokester could paint the mug lightlessness and pen OFF on the side , then pelt in a cup of boil live coffee .
