I have made an amazing discovery! If you take objects and turn their mass into a negative, they still fall like normal, but their collision properties are quite interesting. The borders of the figures act like 'chains', holding them together. Also, when you let an object with a positive mass colide with an object with a negative mass, they eliminate each other, just like matter coliding with anti-matter. When this elimination process ocurrs, it sucks nearby objects towards them. The interesting thing is that if an "anti-matter object" is fixated, it acts like a normal object. For reasons which I do not know, sometimes the elimination process I described earlier does not occur, and when that happens, the "antimatter objects act like they have a negative restitution. Let me know what you think by responding with a comment.
