Here's why:
* Speed of Sound: The speed of sound depends on the medium it travels through. The denser the medium, the faster sound travels.
* Aluminum's Density: Aluminum is the densest material of the three (air, water, and aluminum).
* Faster Travel: Because of its density, sound waves travel faster through aluminum than through water or air.
