Wave Projection Experiment – 25/02/25 – By Fraser Macdonald
Video:
Setup: 3M Overhead Projector with clear acetate basin, filled with water, projecting onto white wall.

Conclusion: Interacting with the water and seeing the peaks of the waves projected onto the wall in real time was engaging and satisfying. I also enjoyed observe the interaction between the peaks, and the way the square basin shapes the waves. When the water is initially poured into the basin, bubbles of air are trapped on the surface, and when they pop, generate circular ripples in an unexpected and very satisfying fashion. A downside to the 3M projector is it is very bright and straining on the eyes to use for prolonged periods of time (I should have worn sunglasses).
Follow up questions: Is there a way to project this downwards on to the floor as in the design? Should use actual water rather than acetate imitating water? How would different basin sizes affect the interaction between the waves?
Next experiment: Wave generation via contact speaker on basin.
