Two students at North Liberty High in Liberty, Missouri, have created a 3D printed ketchup cap that will prevent watery ketchup from squirting out.

Tyler Richards and Jonathan Thompson always hated the watery mess that came out when they squeezed out ketchup. “We both happened to have ketchup-related problems. It’s just the watery stuff whenever you’re trying to squirt ketchup on a hotdog or hamburger bun. Water gets on it and it soaks it up. It’s nasty, said Richards.”   They had a chance to solve the problem during their Project Lead the Way, which is a national education program that takes on a hands-on and project-based approach to STEM education, using technology.

Richards and Thompson spent a week sketching and developing a solution for the ketchup problem. Then, they designed the cap in CAD software and 3D printed the piece, using Stratasys’ Mojo 3D printer. The ketchup cap is shaped like a mushroom, which forces the ketchup away from the cap and into a basin at the center. The water sits there and the ketchup, minus the water, comes out.

Initially, the students’ teacher didn’t approve the project. So Thompson and Richards conducted surveys and research that their theory would be useful, finally convincing their teacher. The students are looking into patenting the design and may start a business from the idea.
