If you like or liked professional wrestling, you might remember the name of technique called “pile driver”.
I did not even think where this comes from but all of a sudden, last week, noticed this is named after a construction machine to pile columns into the ground. It is like a hammer in a huge scale and literary hit the top of a column with a weight. You may recall a huge sound and noise of this machine in construction sites. Now, it is much more quiet and make less vibration as a machine called silent piler was invented.
