Is this egg cracked?

Researchers have developed a technique to find out which eggs are at the highest risk of breakage.

Cracked eggs in the shell cause a huge economic impact for the industry as they are rejected by consumers. In addition, they pose a health risk due to the ease of penetration of bacteria.

To find out if the eggs are cracked, researchers have invented a machine that sends a sound pulse. Analyzing the resonance frequency, the machine sensor calculates the robustness of the shell. This provides for your chance of breakage.

A curious application of echo, right?
