Here's how to make a floating paperclip compass using just a magnet, a paperclip, and a bowl of water. By stroking a paperclip along a magnet, the paperclip becomes magnetized. When floated on water, the paperclip aligns with Earth's magnetic field, pointing north and south—just like a real compass.

This simple experiment builds on the idea of floating a paperclip on water, which uses surface tension, and takes it a step further to explore magnetism and Earth's magnetic field. It's a quick demo with a visual explanation of how a floating paperclip can act as a compass.

Here's a longer video about why the paperclip floats:

Thanks for suggesting this, David!
