Reviveaphone, created by Oliver Murphy and successfully pitched on the British-version of Dragon’s Den last January, provides a surprising fix for repairing a phone that’s been dropped in water or any other kind of liquid. Reviveaphone is a chemical solution that acts directly on the mineral deposits that attach to the circuits of a submerged phone. After soaking for seven minutes in the mineral-dissolving solution followed by 24 hours of drying time, 95% of phones that undergo the treatment are revived.
