This unusual table centerpiece is ephemeral -- but it's beautiful while it lasts.
Using an apple corer, make a hole about halfway through the middle of an apple. Make the hole as straight as possible and remove the core piece.
Insert a candle into the hole. It should fit tightly; if the hole is too large, wrap waxed paper around the candle's end.
Older kids can decorate the apples by carefully carving designs in the skins with the tip of a potato peeler (to prevent the designs from turning brown, rub them with lemon juice).
Arrange the candleholders in a circle on a plate or cutting board.
