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.
