principle

The momentum is conserved during elastic collision. When the mass of the object is the same, the kinetic energy can be exchanged at the same time. The small steel ball fell into the middle of the coin and opened the coin a little. It also bounced off itself. When it fell again, it entered the seam of the coin and the bottle.
