Ball Launcher system “Monkey hunting”


【Product Description】

Balls collision system in the air by projectiles launched at an angle.

【Overall Advantages to Users】

  • The system can show a great demonstration of the two objects collision in the air (one dropped in free fall and other one launched at an angle) to students.
  • The system has been improved to get higher probability the objects hitting each other in the air constantly and has been designed to be bigger for great demonstration in a classroom.


  • Monkey hunting
  • Projectile motion
  • Projectiles launched at horizontally
  • Projectiles launched at an angle
  • Two-dimensional motion




【To all users】

  • A long aiming guide rail (1650mm) raises the collision probability of two balls in the air.
  • Comparison experiments can be easily carried because the ball launching (initial) speed is adjustable in steps.
  • In case of the collision experiment in horizontal position, the guide rail must be hold by a stand because of its legs’ height.
  • The ball dropping device at top of the guide rail and the ball launching device at bottom of the guid rail are controlled by electricity. Therefore, the system needs a DC power supply to operate.

【To teachers】

  • For even higher effectivity demonstration, it is good to take a high speed movie by digital camera or a smart phone.
