So iodine plus starch equals a brown mark on regular paper, but currency paper isn't regular paper. It's actually a mix of fabric fibers and contains no starch.

Footage shows the stunning moment a dynamic colour shift from an iodine clock reaction was captured in China. University students conducted a chemical kinetics experiment by adding three distinct ...
