Tesla coils are beautiful examples of high voltage hardware, throwing sparks and teaching us about all kinds of fancy phenomena. They can also be quite intimidating to build. [William Fraser], howe… ...

By using a Tesla coil modified with a metal wire mesh, the surface of the petri dish is exposed to the coil’s discharge, altering its surface energy and rendering it hydrophilic.

Of course, a Tesla coil is only "like" a transformer. By using higher frequency currents along with a capacitor, even larger electric potentials (and thus large electric fields) can be created.

Explore the power of wireless energy as you build your own ‘baby Tesla coil’ (or Slayer Exciter) using Lego Technic! This experiment may not be a traditional spark-gap Tesla coil, but it ...

Tesla coils do the same thing, but with a much more dramatic change in voltage. First, they employ a pre-made high voltage iron core transformer to go from 120 V wall current to roughly 10,000 V. The ...
