Projectile Array

In the old FMA serries, armstong would punch bricks, and they would combust and fly away. This was impossible!!! His array was made only to change the shape of the rocks so they would become, oh how do you say, arrowdymanic? Sharp? Pokey? Well it wouldn't set any rock on fire. You can see for yourself [link]
This array would do the same thing. If you were to put this on a gauntlet and punch a brick, not only could you make it into a pointy shape, but you could set the end aflame and boost its power. It also has the amazing ability to explode when it hits another object. With this array, the potential is amazing. You can launch wood, rock, wax, glass, poll bottles, and so much more. Now there does exist one problem- Not everything can go BOOM when it hits another object. It also might not be super reactive. Rock and wood would be your best bet for a good BOOM!
