HOPutting ice on gum stuck to your shirt works because cold temperatures harden the gum. Gum is sticky and stretchy when it’s warm, which makes it cling to fabric fibers. Ice rapidly lowers the temperature, causing the gum to stiffen and lose its elasticity.
Once the gum hardens, it can no longer grip the fabric tightly. This makes it easy to scrape or peel off in one piece without spreading or sinking deeper into the fibers, reducing the chance of stains or fabric damage.
