Be sure to have the following supply:
- balloon
- paraffin or candle wax
- a wick

Procedure:

- Make a water balloon by fill the balloon with water.
- Secure the top of the balloon.
- Melt the wax using a double boiler or an old saucepan or an old electric skillet.
- Keep the wax between 165 and 185 degrees until fully melted.
- Let the wax cool until it is just about to set.
- Dip the water balloon in the melted wax and pull it out quickly.
- Let the thin layer of wax on the balloon cool and set.
- Dip the water balloon in the wax again, and let that layer of wax set.
- Continue until you have a nice wax shell around the balloon, about 1 cm thick.
- You can use several different colors if desired, alternating colors as you dip.
- Pop the balloon and remove it from the center of the candle.
- Slowly add warm wax to the inside of the shell, rolling the wax around the edges until it covers the interior.
- When you get to the last pour, place a wick in the center and pour the warm wax around it.
- Hold the wick in place until the wax cools enough to support it.
