Oobleck for Potholes

Oobleck for Potholes

A group Case Western Reserve University undergraduates have created a waterproof Kevlar-reinforced pouch filled with shear-thickening fluid that can be simply dropped into a pothole to effect a quick fix. Under its own weight, the goo flows to take the shape of the pothole. But when a car drives over, it thickens in response to the applied force and supports the weights.

How-To: Low-Cost Gyroscopic Camera Stabilizer

DIY physics guru David Prutchi coveted one of the expensive professional-grade gyroscopic camera stabilizers made by Kenyon Laboratories. “These devices,” he observes, “don’t seem to have changed much since Kenyon’s founder filed the following two patents in the 50′s: US2811042, US2570130.” Referencing those patents, David reverse-engineered the basic geometry of the Kenyon stabilizer using a pair of inexpensive precision gyroscopes from Glenn Turner of gyroscopes.com.
