Subject: [tap-l] cart fan recommendation?

=20

Folks,

=20

Does anyone want to recommend one cart fan system over another?
You know...those little fans you mount on the top of a small
low-friction cart in an introductory lab to give the cart constant
acceleration?

=20

I see the big two are Vernier and Pasco. Does anyone have five
years or so of experience with either (or both) and want to comment?
Are there other fan systems that will fit on a standard Pasco (or
Vernier) cart?

=20

I'm interested in reliability over a four or five year period.

=20

Thanks.

P.S. For the record, I'm a poor community college instructor (oh, whoa
is me!) so solutions like "I went down to my machine shop and built my
own from the ground up" don't do me any good. Well, I guess I could do
that, but, maybe I'm just too lazy. =20
