I'm sure a similar thing could be devised for deskinning garlic....I'm sure I saw something similar using a jar...but when I did it it didn't work. Maybe that could be his next project.

My dad once spent a summer collecting beer cans with the idea to make an airplane that flies over water just using the refracted air (or something like that). He never did get round to it (maybe it was just an excuse to have a load of BBQs), but later in a documentary we saw that the USSR had come up with the same concept and made proper big airplanes that used the technology, so he had been on to something. He also installed a maze of metal vanes behind a fireplace in an extension we got built, had something to do with circulating warm air to het the house, but as with the beer cans he never quite got round to finishing it to get it working. I always thought it a mystery the space hidden in the middle of that house.

I guess for every dad with a great idea who pulls it through to fruition there's another 20 dads with equally great ideas who just let life get in the way of their childhood dreams of being successful crazy inventors.
