Simple 2-Beaker Leyden Capacitor
All you need are two beakers that can nest one within the other, some foil, wire, fur and a pvc rod. An easy reliable leyden jar that works even though the video cuts out during the spark (it was me turning off the lights that messed up the video… not sure why). It’s a small spark, but it’s there. Easy to teach and most all kids have success with this. Foil MUST be tightly wrapped on glass beaker, no air bubbles.
