BUMPER THAT REDUCES THE IMPACT BY 90%?
Łągiewka's bumper is a shock
absorber
which
protects
physical object against effects
of collisions. Inventor of this
method is Lucjan Łągiewka. This
technology allows reducing the
effects of collisions even about
90%. This mechanism reduces
forces and energy which work in
struck
object.
Łągiewka
developed his bumper in the 90s but so far none practical realization of this inventionexists.

Bulletproof vest
The first bulletproof vest in the world has been
created by Poles, precisely Jan Szczepanik and Casimir
Zeglen. Szczepanik reached a conclusion that a vest
that has to stop bullets should be made of the
strongest at that time fabric- silk. The fabric, arranged
in suitable strands, has been strengthened with metal
plates. This is how theoretically a bulletproof vest had
originated. Jan Szczepanik was so confident of ist
effectiveness that he tried it on himself- dressed in his
invention he allowed to be given a gunshot. As you
might guess- nothing happened. Polish vest quite soon
found a practical use. In 1902 bombing assassination
attempt on King Alfonso XIII of Spain failed, because
the monarch was sitting in the carriage lined with a
bulletproof fabric invented already by the Poles.Of
course, today’s bulletproof vest differs from that of
1897. However, the Poles were the first to come up with this idea and produced the first
copy.
