DESCRIPTION

The launcher is aimed at the suspended target.  Set the circuit box so the photogate trigger is armed.  Pull the launcher string up to release the ball.

If desired, use a laser to sight along the launcher.

 

NOTES

Set this up on the demonstration bench behind the chalkboards.

Use the ramrod to load the ball to the medium range of the launcher, with the photogate trigger disarmed.

Don't leave the target on the magnet too long or it may become magnetized and adhere when released.

There is also a stuffed monkey target.
 
Here's a video of Harvard's version of this demo, viewed from both the monkey and hunter's frames of reference, and in slow motion: http://www.youtube.com/watch?v=0jGZnMf3rPo
