1. Place a little bit of hot glue in the center of the container bottom. Stick the wick in it and let the glue set.
2. Cut the gel into small pieces so it melts faster and more evenly. Melt it in a stainless steel pot over a medium heat.
3. The trickiest part is the temperature – you should get it to exactly 200°F, because overheated gel looses its clarity. For that, you will need a suitable thermometer.
