Does gold float in water?
Gold is hydrophobic: it repels water. Because of this, even if the piece of gold is first completely submerged, if it gets near the surface it will throw off the water above it and float. Since most placer gold is flat and thin, its weight is small relative to its circumference so it will usually float.
How do metal detectors detect gold?
Metal detectors work by transmitting an electromagnetic field into the ground, then analyzing the return signal. By measuring the size of the eddy currents and how fast they are traveling, gold detectors can calculate the “time constant” of a target. Time constants can vary considerably between targets.
