Ouch! This is what happens when you rewire a Nerf gun for extra fire power. <br />Think Nerf guns are for kids? Think again. <br /> <br />MegaJAFmanEXE has pimped up his toy and now it’s got ferocious fire power. <br /> <br />By modifying the voltage on the Hail-fire model, he’s been able to increase the speed at which bullets fly out of the gun. <br /> <br />Naturally, he wanted to find out what sort of damage the enhanced model could do, so roped in a friend to shoot at. <br /> <br />The bullets now whizz out so fast that they cause little swollen wounds when they hit the body. <br /> <br />MegaJAFmanEXE slowed his footage right down so you can see the effects of impact. <br /> <br />Obviously we don’t recommend you do this at home, it looks hellish painful. <br /> <br />Ouch.
