Heres a Way to make the best 'semi-explosive poi'

i hav a set of poi which when spun shoot flames and sparks every where

all u need is a ping-pong ball, a poi string with a clamp to attach any thing u want and a small globe (made out of metal that has holes in it and is hollow)

You make the globe with kevlar wrapped around each wire so that you can lite it.
You make holes in the ping-pong ball and fill it up with whatever you want (i use iron filings) and open the globe and put the ball in.
Then you just attach the globe to the poi string or wire.
When you lite the kevlar around the wires of the globe it looks really cool but when you swing it the iron filings fly out and make sparks and fire

Um, what's a globe?

a globe is a circle.
but u need 1 which is just a wire frame of 1.
