The size of the flame can be adjusted during juggling in two ways:

1. The centrifugal force.

Greater centrifugal force gives a bigger flame, and less centrifugal force results in a smaller flame. During juggling, you can create a bigger flame by using juggle moves such as chops, fast doubles or swing moves. You can make the flame smaller by using juggle moves such as high singles, backward rotation or just holding the juggling torches in an upright position. When the flame has reached its maximum size and the wick is saturated, the wick may splash drops of Kerosene if you continue using forceful juggling.

2. The heat from the fire.

By holding the juggling torch at an angle with the wick facing slightly downwards, the flames will be closer to the fuel tank and will heat it up. The greater heat builds an internal pressure resulting in more fluid being transported into the wick and thus a bigger flame. It’s fascinating to watch how the flames just grow.  

”TurboFlame ™”

When approx. 3-4 minutes remain of the burning time the phenomenon “Turbo Flame ™” kicks in.
This means that the flame grows even bigger for about 1-2 minutes and is a great climax to your show.

Important notice!

Use only good quality Kerosene or Paraffin oil or similar inside the fuel tank.
Other fuels like white gas, gasoline etc. are not supported as the different properties make them very dangerous.
These more volatile kinds of fuel can be used on the wick for easier lighting though.
