Device to remove gum from school floors

The Tustin High School InvenTeam invented a device to remove chewing gum from sidewalks and other concrete surfaces. The device incorporates an electric heating element to heat the gum, a biodegradable chemical solvent to loosen the bond between the gum and concrete, and a brass brush to mechanically remove the gum without damaging the concrete. Each piece of gum is removed in 30 seconds. The device has a similar form factor as a household vacuum cleaner and it draws up to 275 amps from an AC wall outlet.

With about 13 days left before we ship our prototype, the InvenTeam is meeting everyday after school and weekends to finish it by cutting, soldering, modeling and assembling all the components together. All of our components work separately and our advisor, Mr. Hernandez is pulling his hair out due to the stress. However, we are confident we can finish this by our goal date.

With 5 weeks left to go, we are on our way to completing our fully functioning prototype. Our heating elements for our first component are complete. Our second component, the liquid chemical storage is finished as well. For our third component, the mechanical abrasion, we are putting on the finishing touches. Our next step now is wiring for our prototype which proves to be a difficult task but the team is confident we can do it. Completing our 3D modelings is also a task needed to be done.

The Tustin High School Inventeam was honored to have met with California's 45th congressional district U.S. representative Mimi Walters for a quick tour of our T-Tech Acedemy shop as well as showcase our gum removal machine.

Last Wednesday, February 22, our team held their Mid-Grant Technical Review in our very own Little Theater. It’s safe to safe to say that the event was a major success. The team met hours before the start of the presentation to set up our banners, tri-fold posters as well as our prototype. Outside, we had a table full of refreshments and snacks as well as our business cards. Many praised our cute and colorful banners and business cards.

Tustin High School InvenTeam is hard at work now that the Mid-Grant Review is just around the corner. In order to prepare for the event, we have discussed about our presentation as well as designed business cards and banners. It is important to use this chance to promote our team and our invention. Our business cards and banners are designed so our social media is listed as well as our gofundme link for donations. Our banners are also eye-catching and livens up the event.
