Fireballs are one of our most spectacular indoor effects - pillars of coloured flame topped by a "mushroom cloud". They were first developed to depict nuclear blasts in a stage version of When the Wind Blows. Fireballs produce very little smoke, the orange ones being smoke free.
The flame rises from 2 - 2.5 metres, with a little debris projected higher. We have a "double size" version which is not much higher but produces a bigger, wider cloud.
A whistling "whoop" sound is produced as they fire.
We have just improved our range of colours. Blue and yellow are now available in addition to white, orange, red and green, and the red and green are more intense than they used to be.
