Patent 7,080,668 non-baseball thing

This is kind of cool. I just received US patent protection for an idea I submitted in 2003. The idea was a safer way to fill a liquid nitrogen tank (Dewer). Liquid nitrogen is kept very cold -196C and if you've ever seen the science experiment of dipping an egg in liquid nitrogen and seeing it shatter like glass then you know that if spilled the LN is unforgiving.

When I told my mother she was not surprised and claimed responsibility for my creative side. She did not like my comment that, because of her, I had a lot of experience dealing things that were extremely cold.
