Red Green Ball Black Wave.
Green ball balancing on top of the wave. Tension is rising as the question is if the ball is going to fall of the wave or does it manage to stay on top. It may be a shock if the green ball gets hit by the same disappointment and crashes to the bottom with the risk that it is going to be engulfed by the crest of the wave.
It is only going to survive if it manages to stay on the top.
