6. Loosen stuck bolts
Anyone who’s ever done some home improvement or basic auto maintenance knows that stuck bolts can be every wrench-turner’s worst enemy. If you’re fresh out of PB B'laster or Liquid Wrench, try some Coke. Just like on those old bike spokes, the phosphoric acid will react with the rust and free those pesky bolts.
7. Get gum out of your hair
When mayonnaise, peanut butter, and whatever other gross things the Internet says will get gum out of your hair fail, try drizzling some Coca-Cola into your hair. The ingredients in the Coke will break down the gum and hopefully save you an emergency barbershop stop. It also works great for gum stuck on shoes!
