No its not, this is harsh...Take a 12 gram co2 bottle for those air pistols and bust the top off of it and let all the co2 out. Then Either fill with gunpowder or grind up the engines to those model rockets and fill that bitch up. Get a wick a ma thingy from a fire cracker and light that bitch and run. That shit is like dynamite. Just duct tape him to one of those.
