And this is exactly why I haven't even bothered with the formulas or that line of thinking because all you have to do is use some common sense and the laws of physics and conservation of mass and energy to realize this is the case, which I already pointed out. Energy MUST go somewhere, and the BBBMax product logically transfers more of it to a RIGID target because of the rigidity and non-deforming nature of the product.

To understand it without formulas all you have to do is look at a car accident and look at what crumple zones do to understand how energy is dissipated through object deformation. This is why people survive and walk away from 60km/h head-on collisions. The car absorbs the energy though purpose engineered frames that remain rigid until the application of a suitable force from a predetermined direction...

... much like a plastic BB! Wow. who'da thunk it.
