MAGNETIC GUN throwing rocks

This is a very powerful magnetic gun, uses the attractive force of the magnets to throw anything you can find in the tube. The fixed magnets to the tube all have the same polarity, in fact build the cannon was not easy because of the repulsive effect of the magnets. The magnet insert in the tube has opposite polarity than the other, so that the entry in forcing this tube enters with force between the other magnets with pushing force whatever is in the tube. Very funny 🙂

I used 15 magnets of this type
