The Magnet Dart Launcher
MAGNETIC DARTS Magnet Arrow Launcher Experiment
WARNING!!! This experiment can be dangerous, I recommend anyone to try it without nails
WOW, I discovered this magnetic effect almost by chance by testing for another experiment. it is amazing how fast the arrow is shot from the magnets with hole. To obtain the weapon effect, the arrow and the launcher must have the same polarity. If the polarities are opposite you still get a nice effect like a tractor beam.
