I mod a mcdonalds Mini Nerf Table-top Cannon --power boost--.

I buy a Happy Meal Nerf toy; but it doesn't shoot far at all :-( I set out to change that :-) Note: after removing the screws, splitting the unit in half is pretty difficult. Wear gloves and saw the bottom, then stick in something to pry it apart.
