If jet turbines are the evolution of a propeller, what’s the evolution of ionic thrust? This video explores that question by building and testing a next‑generation ionic thruster with the creator ...

In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music—it's the "Morning" prelude from Peer Gynt, played on an ionic speaker. No ...

It may be hard to believe, but that transparent disk in the photo above is actually a fully functioning speaker. A team of researchers at Harvard's School of Engineering and Applied Sciences have ...

Can be used to recap on ionic compounds or could lead into a classroom discussion on chemical changes and structures.
