Fireball is a battery operated unit that will fire off a ball of fire at your command. This is a great unit to place hidden on your table, in a prop; this unit should not be used on your body, only for props or as a stage flash pot. You receive a black box housing with an easily found black button for sure-fire activation. Attached to the box is a long cord that can be placed in a prop, behind a prop, hidden in your table; used as a flash pot, etc. Pressing the button fires off a ball of fire.
