The first most important invention I learned about was John Kay‘s flying shuttle from lesson #131 of the 4th grade class. I learned that patents aren’t always a good thing. Kay almost went bankrupt from patent lawsuits. A group of men were trying to infringe on the patent and Kay spent all his money trying to keep them from doing so. I don’t think I will patent any inventions that I come up with.
The second is the ice cream maker. This invention was from lesson #54 of the 5th grade class. Nancy Johnson didn’t appear to be very rich or have much funding, but she was still able to invent the ice cream maker. This lesson proves that ANYONE with a good idea can invent. Man or woman, boy or girl, young or old, all you need is a good idea.
