One large orange with the insides scraped out.
For the candle:
Leftover unscented candles with some wax still left around the sides or bottom
New wicks from a craft store
A microwave safe container that you are comfortable tossing or using just for candles
Cut the orange in half and scrape the insides out with a spoon. Set aside.
Using a spoon, dig out all of the wax from each candle.
Microwave wax in a microwave-safe dish in 1-minute increments at about 60% power. It will take about 4 minutes to melt down.
Place a wick in the sliced and scraped oranges.
Once the wax is melted, hold on to the wick with one hand and slowly pour the wax into the orange with the other hand.
Place in the refrigerator for 10 minutes or until the wax has hardened.
