all you have to do is light the sparkler and step away, or throw it (careful not to breath the smoke).
i also made a barrel for it out of 20mm pvc
the 15 mm pvc is the grenade.
light the sparkler and place the grenade inside the hole in the barrel.
when the sparks are about to go through the tape quickly cover the gap with the 20mm pvc and hold it with your hand, or make something better, so that when you shoot the air wont come out of the hole. if you are too slow to do that.......
you will have to make another barrel because it will warp, but dont worry, pvc is sorta heat resistant (as i found out when i done it cus i forgot to pump first)
there will be a lot of criticism bout safety and stuff, but im open
