Commonly associated with classroom blackboards and sidewalk art, chalk can also be used to repel ants from invading your home, lift grease stains from clothes, prevent your tools from rusting, and hide your wall scrapes and nicks in a pinch.
To prevent mustiness in your closet, hang a bundle of chalk inside, which helps absorb moisture and keep humidity away. To stabilize your screwdriver before tightening screws, rub some chalk on the end so that your screwdriver will be less slippery.
