The video shows the surface of a material that was originally graphite, and how its appearance changes in waves. Above the footage, changes in voltage are displayed. When the voltage is high, many ...

Self‐oscillating gels represent a groundbreaking class of smart materials that convert chemical energy directly into mechanical motion. Central to their function is the Belousov–Zhabotinsky (BZ) ...

Oscillating chemical systems are present at nearly every popular chemistry exhibition – especially the ones that display striking colour changes. But so far there are very few practical uses for these ...

Short demo: The fan in a vacuum pushes air out, creating a system of low pressure. This in turn creates a system of low pressure within the bag, allowing for an entertaining demonstration of the power ...
