dramatizing Coulomb repulsion and charge distribution on conductors

Demonstrates that horizontal velocity is independent of vertical motion by ejecting a ball vertically from a moving aluminum car

sized for the next step up from the 100uA meter when small-signal circuits exceed its full-scale deflection

Compact-format sonometer designed to study the physics of vibrating strings on a footprint smaller than the standard 1-meter teaching unit

Demonstrates electromagnetic induction and Faraday's law by stepping DC input into 25mm high-voltage sparks across adjustable electrode rods on an open chassis
