Yes. When I was about 13, one of my relatives stuck his hand into a metal fan while it was on. This led me to design a fan with rubber or fabric blades. I submitted the design to some companies, but they showed no interest. Shortly after that, the product came out on the market. This was my introduction to the market place.

Once when I was 10, I designed a special candle for a religious sect in New York City. They weren’t permitted to put out a candle on their holy days, so I designed one that would self extinguish at any hour they desired. I timed the burning of the candle for whatever amount of time was needed. Then I cut the wick at different points in the candle that correlated with different times and pulled the remaining wick out from the bottom of the candle.
