US scientists invent temperature-controlled "coffee beans" to keep the best taste
Don't be afraid of burning your tongue when drinking coffee! Several American scientists have designed a metal "coffee bean" called "Julie", which has the magical function of controlling temperature. As long as you put it gently into the cup, the hot coffee will automatically become the best taste of 60 degrees Celsius.
According to the American Journal of popular Science on April 1, the metal gadget designed in the shape of coffee beans has a temperature-changing material in its shell. When the coffee temperature exceeds 60 degrees, the material melts and absorbs calories until the coffee is cooled to 60 degrees. Below 60 degrees Celsius, the material will condense and release heat to "heat" the coffee. It is in this way that the coffee can be kept at the best temperature, and you can take your time reading the newspaper while enjoying the delicious coffee. Scientists also designed matching insulation cups.
The invention has so far raised 35000 US dollars and is expected to be mass produced in the near future. It may become an indispensable "coffee companion" for coffee lovers in the future.
