Fireballs are a fabulous prop, despite what you all say. After experimenting every night for two weeks, I finally learned the secrets of how to juggle them, and can now do five.  I would tell you all, but then they wouldn't be secrets anymore.  I want to savor it for a bit longer before I divulge the trick, but I will give you a few tips.

-Lamp Oil (Paraffin) is the best fuel.

-Damaged balls can be fixed with silicone sealant. 

-Don't hold on to a lit ball too long lest you burn yourself.  

 -Solarcaine Medicated First Aid Spray is excellent for treating burns.                                                

-FireBalls look more impressive at night.
