How to Make a Simple Water Compass for Navigation #1483550 (License: Personal Use)

This illustration shows a classic water compass setup-a magnetized needle or cork-and-needle assembly floating on the surface of still water inside a non-metallic bowl. The needle rotates freely until it aligns with Earth’s magnetic field, with one end pointing toward magnetic north, as indicated by the labeled arrow. This low-tech method demonstrates fundamental principles of magnetism and has been used historically for orientation in the absence of modern tools.

Used in educational science content, survival guides, and outdoor navigation tutorials; targets students, teachers, hikers, and preppers seeking foundational knowledge of magnetism and direction-finding.
