We've just been using old 0.5mw Metrologic HeNe's, but it is a human hair a=
nd is just an optional part of the lab.

Subject: [tap-l] Hair diffraction lab

While I've been providing the community with cat whiskers for several years=
for this lab, I've never actually done it (hence why I give all my whisker=
s away!). Am I assuming correctly that a simple laser pointer work decently=
well enough for this... even the cheap "cat toy" lasers?

If anyone has this lab to share with me, that'd be great, too!
