As a student, he brought to the class two completely identical round expander, but their similarity in appearance and ended - one was very light, the other - could be compressed by force no more than 10 times.
There was no pre-created insidious plan, it arose on the move, when a classmate (athlete, fighter) offered to compete. Immediately outlined the conditions - who will last longer, repeating one after another the compression of the expander.
The result is obvious, isn’t it? Immediately after my victory followed the exposure of the foundation – it was painful to watch a man who thought he was strong enough to break down.
