Abstract

A chemical wave was initiated in a system (glass tube or graduated cylinder) containing a water solution of potassium iodate, potassium hydrogen sulfate, starch, and an excess of potassium arsenite. A large number of photos (329) were taken with a digital camera (one snapshot every 30 seconds). These photos were linked to give a unique video clip. This video clip may be used as a time-saving alternative to the classical demonstration. Similar clips may be made for other long-lasting processes.
