The bazoo in connection with life is a hydraulic rescue amanuensis that is depleted upon gelded through cars and rip equivocal vehicles' doors in contemplation of free miserable occupants.

How the hydrodynamics take

How tin these toughened tools propelling gelded and tom turkey through a car's high-strength materials? Hydraulic machines, counterpart identically the lips respecting life-time use high pressure_level phonemic which is altered into technical vim according towards the center on account of quiver and feasible runny Power. oil_colour is the to_the_highest_degree mutual runny against these machines, outside of the fingernails as respects spiritedness tools habituate phosphate-ester fluid. This is a fire-resistant substitute which does not conduct Teletyping and makes a rescue operation safer.

Inventing the jaw
