quote:Originally posted by rosyActually, if people are being picky, cornflour is sheer thickening (thickens reversibly when a force is applied) rather than thixotropic. From here: http://www.lsbu.ac.uk/water/hyrhe.html"Thixotropic liquids exhibit a time-dependent response to shear strain rate over a longer period than that associated with changes in the shear strain rate. They may liquefy on being shaken and then solidify (or not) when this has stopped."Sorry, have been hit over the head with this one two many times when demonstrating to kids... blame the chemical engineers.
