| Geoff - cornstarch is the stuff you are thinking of - a non-Newtonian Fluid (not liquid). Actually a colloidal suspension - the individual particles in the suspension will slide slowly past each other but resist rapid displacement. This only happens when the fluid has a certain concentration of starch to water. It is great to demonstrate the principles of non-Newtonian fluids but not very stable. I would stick to basic fluidics or hydraulics, using variable restrictions. The SCAT release uses a similar principle, but backwards, so a timed release happens after the trigger is released as opposed to applying pressure to the release and waiting. Good luck!
