Porosity and Permeability Lab Activity Forensic Chemistry and a structural engineering demonstration

and a structural engineering demonstration of uniform scaling and transformable linkages for older ones

Make wave motion and resonance feel immediate with a compact electromechanical driver that turns a signal into visible vibration

Please note: This version of the Miniature Digital Voltmeter is no longer available

The ringer is mounted on rubber feet to dampen the vibrations

This modern version of the classic bulb-and-gauge setup features a built-in digital pressure display
