Four Chladni plates of different shapes — circular, square, triangular, and violin-shaped — each mounted on a clear cylindrical audio driver, showing sand patterns at resonant frequencies

Chladni Figures

Sand on a vibrating plate collects along nodal lines, revealing 2D standing wave patterns. Students see how plate geometry and driving frequency determine the mode shapes, connecting resonance and boundary …

Three wooden organ pipes of increasing length lying on a green surface; the smallest has a removable stop, the middle one has a thin wood membrane panel, and the longest has a glass window

Safety

Special Organ Pipes

Three specialized wooden organ pipes designed to illustrate open vs. closed pipe resonance and visualize standing wave nodes using sand and cork dust. **Note: All three pipes are currently non-functional …
