Rebound Striking
Question:
Can you hit the red ball with
the white ball by going around over the obstacles?
Instructions:
1. Put
the white ball in the trigger. Pull the trigger backwards
and aim it at the red ball. Press the button to release
the white ball.
2.
Put the yellow, green and brown obstacles in the same
coloured box in turn. Can you hit the red ball now?
3.
Plug the mirrors in the slot of the same colour. Repeat
step 2. Which way is easier?
Why?
In the absence of sideway spin,
the ball when hitting a hard surface should follow a path
similar to that of light ray, i.e., the angle of reflection
equals the angle of incidence. All you need to do is to
aim your trigger at the red ball image, then the ball
will act as if it were light and hit the red ball.
