We have come up with six similar hacks that show you how to use eggshells in the garden and to make fairy lights, candles and more. Try out these hacks at your leisure, though some of them are too fun to resist.

Method 1: Eggshell Fairy Lights

Ostrich eggshells have long been used to make artistic lamps, but you don’t have to go that far. If you have some eggs in your refrigerator, you can use their shells to give a truly magical twist to a string of fairy lights.

All you need is a string of fairy lights, a hot glue gun, and eggs and you’ve got easy egg-themed lighting for your next Easter party.

Note: Kids should use hot glue gun under adult supervision. Use LED fairy lights for this project as normal lights will heat up the eggshells, causing cracks to appear in them.

Things you’ll need:

Method 2: Eggshell Candles

If you are into candle-making and were impressed by eggshell fairy lights, then you will also love learning how to use eggshells to make candles. All you need to do is use empty eggshells as the containers to hold the wax. You can go with any candle-wax mixture, but we’re using beeswax and olive oil.

The length of the wick should be more than you actually need. That’s because you can trim extra wick when you’re done, but you won’t be able to compensate for short wick in the middle of the process.

Toothpick has many handy hacks including helping you keep your wick centered. A chrome nut can help you weigh down the wick, so it won’t float about on the melted wax.

Things you’ll need:

  • Chrome nuts

Step 1. Tie chrome nut and toothpick to either end of the wick

Step 2. Set the wick into the eggshell

  • Make sure that the wick stands in the center of the eggshell.
  • Prepare as many eggshells in this manner as you need to make the required number of candles.
