Measure twice the volume of the amount of wax you’d like in each glass vessel and melt on the lowest setting in a saucepan. Use a stir stick to stir the wax occasionally.
While the wax is melting, place a wick in each glass tumbler. To do so, first thread the wick through the metal wick plate. Then, wrap the excess wick around a pencil, and rest the pencil on the opening of the tumbler. If you don’t want to use a metal wick place, hot glue your wax to the bottom of the glass instead to hold the wick in place.
Once the wax is melted, remove from heat and dip each metal wick plate in the wax. Then, adhere to the bottom of the glass.
By this time, the wax will have cooled slightly, and we’re ready to add the essential oil. I used roughly 150 drops (50 drops per 1 cup unmelted wax chips) to make sure they’d pack enough punch to keep the mosquitoes away. Add the essential oil drops right into the saucepan of wax and give it a stir.
Divide the the wax between the glass tumblers.
Center the wicks.
Allow the wax to cool for about 2 hours.
While the wax is cooling, prepare the balloons by trimming off the neck of the balloon and the bottom point with a scissors.
When the wax has cooled, trim the wicks to 1/4″ with a scissors.
Stretch and slide the balloon onto the bottom 1/3 of the glass. It’ll take a little adjusting to get it into place.
