Don’t toss your eggshells—reuse them! They’re great as garden fertilizer, slug repellent, or compost. Crushed shells can clean pots, remove stains, or soften coffee. Use them in crafts, feed chickens, sharpen blades, or make seed starters. For health, try a calcium paste for teeth or use them to draw out splinters. You can even dissolve them in vinegar for fun science. Eggshells are a simple way to reduce waste and add value around the home.
