Sometimes, you want to drink a beverage, but it’s too hot.
You could just wait for it to cool off naturally, but who has time for that!
And if you were drinking from an insulated thermos, this cooling-off process could take hours.
The basic idea is simple: an ultra-long curly straw that would give the liquid some extra time to cool down as it leaves the cup (Figure 1).
However, a standard curly straw will have a minimal cooling effect. Thus, an array of heat sinks are added to the straw, as shown in Figure 2.
Alternatively, a telescoping design could allow the enjoyment of both hot and cold beverages using the same straw (Figure 3).
Don’t drink from a cup or bowl like an animal—only use this fancy straw for your future beverage needs!
PROS: Cools liquid to the optimal temperature for maximum efficiency of consumption. If widespread distribution can be achieved, it will save millions of hours per year (worldwide) that otherwise would have been spent waiting for drinks to cool.
