Message deploying missile.

I made this rocket that shoots out a meesage from the back when it hits its target. It has a plunger that pushes the message out when it hits its target. I know the tip is not aerodynamic but I did it this way so the plunger could have a lot of surface area. It is meant to be shot out of a PVC paintball gun with a inner diameter of about 25 mm. There is also a plunger on the inside to insure that the message is pushed out. To assemble this glue the smaller plunger to the rod and feed it in from the inside of the body. Then glue the bigger disk onto the part of the rod that is sticking out on the front of the rocket. NOTE: I have not tested this but I have tried the non message rocket prototype.
