6 Inventions By Minnesotans

My husband had a class in high school that they had to invent something. His teacher said that group had a very marketable product. That is kind of cool to hear that a product you helped come with is marketable. So many inventions are out there, do you sometimes think, "What else?" Of course, there is more. Minnesotans have had a few inventions according to minnesotafunfacts.
