Ice Cream Maker
Before Johnson's invention, ice cream was only made for the most royal of people and it was made through a combination of milk, cream, butter, and eggs. Nancy M. Johnson made a hand-cranked machine with a handle on top that would create ice cream, it was made out of wood and some metal. The Ice Cream Maker is used by filling it up with milk, sugar, and some flavoring. Then you turn the handle on the top to crank the paddle inside. The paddle would assists with the churning of the mixture inside and it would scrape off any matter sticking to the side of the cylinder so that no ingredients would go unused. Then you'll be left with only ice cream inside for you to eat.
