AKA: Howitzer and Tunnel
Courses: P3, P13.
A Pasco cart carries a launcher that automatically triggers when the cart passes a set point. A ball is launched vertically, and lands back in the cart some distance further down the track. This can be further enhanced by placing a tunnel over the track for the cart to pass through after launching the ball and before catching the ball.
Position the track so the white ball will be against a black background, for visibility.
Note: this requires some adjustment of the launcher to make sure the ball is being fired straight upward.
