If you like to perform holiday demonstrations, this one’s for you! In this demonstration, a flask containing a clear solution is shaken, turning the solution into a pink valentine solution. Then, by allowing the solution to sit undisturbed, it will fade back to colorless. The cycle can be repeated many times.
