Dissolved corn starch is a non-Newtonian fluid that turns solid under sudden force. We've seen how you can run a cross a pool of it, but a slow walk will mean you are swimming. What would happen if you forced it through an extruder with a hydraulic press? Lauri Vuohensilta shows us with his hydraulic press.
After the cornstarch, he has some fun with color-changing putty, cheese, ballistic gel, crayons, canned shaving cream, and soap bars, all which go through the extruder. (Thanks, Edward!)
