Magic Faucet / Faucet

Keeping hands clean is essential to avoid getting sick and transferring bacteria to others. While due to the invisibility of bacteria, most people carelessly wash hands and hardly realize how dirty their hands are. To tackle the problem, we designed this Magic Faucet, which can emit excitation light with special wavelength to scan hands and interact with bacteria to make them glow. So bacteria on hands can be seen directly by eyes, showing us where bacteria are distributed and whether we have washed our hands clean enough. With this faucet, people can maintain hand hygiene, form a good hand-washing habit, and reduce the spread of diseases.
