High Schoolers Use 3D Printing To Solve The Most Annoying Thing About Ketchup [Video]

Two students at North Liberty High School in Missouri designed a 3D-printed cap insert that keeps water inside the bottle.

North Liberty High School seniors Tyler Richards and Jonathan Thompson have designed a 3D-printed solution to the age old problem of ketchup in a bottle – that watery mess from the first squeeze.

The students designed a 3D-printed cap insert that is shaped like an inverted mushroom and creates a sort of stopper for the nozzle of the bottle. The ketchup is pushed up and over it as it is squeezed out of the bottle and the water collects at the bottom and is prevented from being squeezed out with the ketchup.


Richards and Thompson are students at their school’s Project Lead The Way program, a national program that adopts a project-based approach to science, technology, engineering, and math (STEM) education for students from elementary to high school.

The two students created over 60 designs for the solution before narrowing it down to five and then deciding on a final design. According to Thompson the design is based on the pythagorean cup idea and works on the same principle used in toilets. They created the design using a computer-assisted design software and produced a prototype using a 3D-printer.
