Mythbusters season 2 episode 9

Four smaller myths put in on episode. Number one shooting a sniper through his scope. The lenses in the scope work as shield and stopped the bullet so that myth was busted. Number two hitting two hammers together making them explode. No matter what they did the only results was a few small fragments. Number 3 shooting a bullet into another persons gun. The results looked just like the picture had but it took a lot of work so it is plausible. Number four making two musket rounds fuse together . Because of delay it took a long time to make work but after awhile it was announced confirm when they found to bullets stuck together.
