    Completely baseless assumption, but I think it’s just a continuation of the phenomenon when toddlers get hyped for trucks/tractors/combine harvesters/anything that is big and loud, maybe because it’s associated with power, I don’t know. Some people just stay at this toddler’s mentality and they see everything that’s big and/or loud as something you can boast about. See also: loud exhausts, 6400 deciBel motorcycle sounds, etc.











  • I’ve watched a video about this recently. The problem is, most detectors were based on X-rays in the past decades. Liquid explosives are pretty close to the density (and/or other properties) of water, and you can’t tell for sure whether there’s toothpaste or boom juice in that tube.

    However, some airports started using expensive MRI MRI like X-ray* machines that can see stuff in more detail, plus, it lets you to make cross sections from different angles and therefore have a 3D model that you can rotate on your screen (it’s rather cool).

    EDIT: I just realised someone else linked this, too. I would leave it here, it’s still educational.
