Scientists have claimed that they have found a fast way to detect explosive liquids on an airplane. They call this process Hilbert spectroscopy.
All materials reflect light in a unique way and this devise will help to identify certain liquids based on their light reflection. This in turn provides a chemical "fingerprint" of the item being analysed.
Further developments are necessary to refine the approach. But the researchers are confident the technique can be applied to security screening.
However, the overall process of the screening is either too expensive or too time consuming to be done to every piece of luggage.
I like the idea behind this article because I hate buying a beverage in the air terminal and then being asked to disguard it upon boarding the plane. Airlines really find all way to take your money. I feel that this would stop that problem most people have and they would be able to identify normal liquids and liquids that could be dangerous.
