Have you ever wondered how those tiny beads of ice cream that you can buy at the mall and amusement parks are made? Dippin’ Dots are cryogenically frozen ice cream balls made with the same ingredients as regular ice cream. The ice cream treat was invented by microbiologist Curt Jones in 1987.
In 1987, Jones was working on research for new techniques for freezing bacteria on a large scale. He developed a process for making cattle feed by freezing it in chucks at 350-degrees below zero to preserve the nutritional content. One day, while making ice cream with his neighbor, he had an idea to use a flash-freezing technique to freeze the ice cream. The frozen treat would retain the flavor of ice cream but have none of the iciness.
Six months of research and experimentation resulted in Dippin’ Dots. Flash-freezing the ice cream in liquid nitrogen produced hard balls about the size of a pea. The treat which is stored at 40 degrees below zero and served at 20 below keeps it shape for about 10 minutes at room temperature. The beads slowly melt when eaten.

We have just introduced the Patent Cube to the world. This beauty is a 4” x 4” x 4” solid granite hand-polished cube which features a medallion of the United States Patent and Trademark Office seal die struck and plated with 24kt gold. The sides of the cube can be engraved with your name, patent details or even a company logo. We can engrave practically anything on the sides of the cube in our state-of-the-art manufacturing facility…just ask.
