Explore how waves detect objects

The String Wave Spinner is a mechanical wave demonstration device designed to produce continuous transverse waves and standing wave patterns on a string. Attached to a standard drill, the L-shaped spinner drives oscillations through 12 feet of neon nylon string, allowing students to observe nodes and antinodes as frequency changes. Students can relate frequency and wavelength.

(Standard drill required but not included.)

Why Teachers Love the String Wave Spinner

• Clear, high-visibility standing waves – Continuous oscillations produce distinct nodes and antinodes that are easy for the whole class to observe.

• Adjustable Frequency for Real-Time Investigation – Changing drill speed allows students to directly explore how frequency affects wavelength while wave speed remains constant.

• Turnkey & Durable Design – The 12 ft neon nylon string and drill-mounted spinner eliminate complicated setup, making wave demos consistent and repeatable.
