Old chewing gum transformed into skateboard wheels
The used gum is cleaned, treated with a stabilising agent, heated and remoulded to form skateboard wheels
Efforts to rid city streets of chewing gum are as old as gum itself. Modern chewing gum is made from synthetic rubbers that can take 50 years to start decomposing, making it a long-term mess. Now, two students at the School of Design in Nantes, France, have developed a plan to collect wads of used chewing gum and repurpose it into skateboard wheels.
