Sirs... Time Warp is absolutely fantastic. I have a suggestion. you must have noticed kids playing with a heap of coins designed like the PISA tower!!!!??! yes my suggestion is that there may be say 20 coins neatly kept one above the other... now take another coin and strike the TOWER of coins with that coin like playing CARROM. if your strike will be perfect, then the tower of coins will not fall instead the bottom most coin will bw replaced by your coin which was struck by your fingers.. the fact is that no one knows the physics how it works.. i think it will be finally revealed on TIME WARP.
