As fruits and vegetables ripen, they change color due to the four families of pigments: chlorophyll (green), carotenoids (yellow, red, orange), flavonoids (red, blue, purple), betalain (red, yellow, purple). These pigments are groups […]

In this project we will see how to simplify the process by creating a device that accurately measures cuts every time. You won’t […]

An important point though is that these purchasable food dispensers are generally designed for specific applications, for example the […]

As you see in the video you can do it, but why? It is mentioned that the change is due to complex fluid dynamics reasons. Beyond the scientific investigation, the question we asked ourselves was: is this ability to “listen to temperatures” something that […]
