Ice Cream Machine (ICM)

Built by Mr. Rosebank over the last 50 years.
He made the prototype when he was in elementary school, winning the school science competition.
In middle-school he’d upgraded it, and by the time he was junior, it was a fully-functioning device making over 100 ice cream a day.
Highly sophisticated device, believed to contain more ossicles per cubic foot than any other known electronic device.
