Physics Experiments To Inspire Undergraduates?

PShardlow writes "I have recently been asked to propose two projects for a 1st year undergraduate teaching laboratory in the summer term this year. These are projects that a pair of students will spend 36 hours working on, and as such can be quite in-depth. A good project would include something they can build, something they can measure, and something they can calculate. Previous projects have included cloud chambers, a Jacobs ladder, a laser Doppler speed camera, laser sound detection, smoke rings, and physical random number generators. This is an opportunity to really inspire students into the joy that can be experimental physics — but it only works if we demonstrators propose interesting projects. So I ask the Slashdot community for suggestions of fascinating projects to do, things that are relevant to today's physics problems but could feasibly be completed by a pair of first-year undergraduates in 72 man hours."

Perhaps a collection of "The Amateur Scientist" columns from Scientific American would be a good source of ideas? A CD of the columns has been published.

Bell's Inequality and entanglement

[xPsi]

Here are a doublet of papers for an undergraduate laboratory demonstrating Bell's Inequality and and entangled photons. The whole apparatus (detailed in the second paper) is estimated to cost USD 15k circa 2002, so the optical elements have probably come down in price since then.
