Think Ink

From colorless to black and back again, this twist on the classic clock reaction is a must-do for any science enthusiast.

Two clear liquids are mixed together and the audience is told to watch closely… “Don't take your eyes off the liquid or you'll miss it!” Then, in a flash, the clear water changes to ink (or so they think!). Think Ink! illustrates the amazing chemistry behind the classic clock reaction where molecules meet up and change over time to create this startling effect.
