"I’ll wrap this post with a mention of a great inventor who’s quiet demeanor had no bearing on the punch he was packing in the Shark Tank casting session.  Rick Rubin IS 

AutoWrapTec (autowraptec.com).  

Mr. Rubin actually makes things. Machines to be specific-his entire career .     One day a friend was watching bus boys at a hotel take silverware and roll it in napkins and tape it all together.  His first thought was ‘ewe, not very sanitary.’  So Rick went to work and made a portable machine that sterilizes and wraps silverware.  You can imagine the applications, Rick and his partner definitely have.  They’ve already sold several of these custom machines in the last few years.  Think cruise ships, hotels, restaurants, schools, stadiums, catering companies and beyond.   He’s looking for investment to improve the machine, make more and sell more.   Auto Wrap Tec is such a great idea you can’t believe it hasn’t been done, which is essentially what the casting director told him.   You can sue me, but Mr.Rubin was in the room a long time and I am almost sure we will be seeing him on TV."
