Alright so I thought of this the other night.
It's similar to the water filled balloon shot with an arrow.
Fill one, or a few balloons with either liquid or gas, flamable substance, like gasoline.
Then, take an arrow, light the tip, and shoot the balloons, while being filmed, and watch in slow motion.
This could either be extremely cool, or just another explosion.

Question:
What do you think?
Cool or no?

Choices:
Would be very cool, put it on show
Could be cool
No seems like "just another explosion."
Wouldn't be cool at all
