Cavitation Lessons

  [vote for,

The mantis shrimp can impact another thing (life form, aquarium glass) by hitting it with such speed that it shoots vapour bubbles along with the claw, which cause a cavitation impact, even if the claw misses the target.

Surely it can’t be that difficult to learn to do that? As a human, we have flexible and very configurable hands and arms, and it is possible that it is possible to advertise lessons to learn to manipulate the air around us such as to send cavitation bubbles of air through the air, toward a target. It might prove that it’s not possible to do that with our hands and fingers, but it might work with our mouths, which are probably more idealer. Or any other similar bodily orifice.

       You don't know what you're missing, seriously - ask [MB]. He had a smile on his face for weeks afterwards (except when he tried to sit down, but the ointment and the steroid injections eventually reduced most of the oedema).   

       We were going to put the video on YouTube but apparently they have all these stupid "rules" ...
