Want to know how much caffeine is in your coffee? Caffeine Orange will help you solve this problem. It is reported that Caffeine Orange is a tool to detect caffeine. The user drops a little of the coffee liquid to be tested into a groove in the test plate and shakes it.

In order to make the tool available to ordinary people, researchers have developed a way to interpret caffeine content with green pointers-if the color is red, the caffeine content is very high; if it is yellow, then the content is moderate; if it is green, it means it is very low.

The researchers say Caffeine Orange will be able to detect caffeine not only in coffee, but also in tea, sodas and energy drinks. People can use this tool to better regulate their daily caffeine intake.
