Two Brazilian inventors, Natasha Jones Zago and Ana Carolina Calixto, have developed a chewing gum that gains strength the more it is chewed, allowing it to be used to fix materials like steel, wood, and bricks. Their gum is meant to be portable, solving accidental issues like flat tires or holes by providing insulation, filling, and repairs. It aims to simplify complications through an invention that combines the convenience of chewing gum with multi-purpose adhesive properties.
