Not long ago, researchers from King Abdullah University of Science and Technology captured a magic moment with a high-speed camera: droplets of water dropped onto a special powder plane after the first rebound, instantaneously "solidified" and kept bouncing shape. Thanks to this water repellent powder, this phenomenon can completely envelop the entire droplet and maintain its shape at the moment of impact. It is worth mentioning that this phenomenon has many limitations, such as only applicable to the first impact; the minimum impact rate is 5.25 feet per second, etc. Even so, it has positive significance for water cooling technology and aircraft aerodynamics. . For cooking purposes- to measure the temperature inside an oven-, you need a thermometer with special characteristics. First, you need something that has a much higher temperature range than your typical household thermometer. Best oven thermometers typically have a range that goes from 50 to 300 degrees Celsius or 100 to 550 degrees Fahrenheit.

The mechanism that makes an oven thermometer work is also different from traditional thermometers. Instead of infrared sensors of mercury, they have a strip made of two pressed-together metals that expand and contract at different temperatures. This movement makes the dials of the face move to the right temperature indicator. Easy, right? Now to choose the best and most accurate one.
