Thanks for the correction, Martin. You're of course right, now that I think back on it. The VW in the air definitely made a lasting impression, even if an inaccurate one.
Wasn't there a science center somewhere that did have a long lever where visitors could lift up a platform with a car or truck on it? Or did I just wish for that when I was at Science City?

The Nauticus exhibit shows the comparison weight of a Battleship shell and a classic VW Beetle. The exhibit is fixed, not interactive, and merely shows the equivalent weight/balance. I do have a pretty lame, low quality picture I can send upon request.

Science City in Kansas City has some nice pulley chairs that work well.
I think Nauticus in VA (Norfolk?) has an exhibit where a VW bug is being lifted up, if I remember correctly. I'm trying to remember if guests could use the pulley to lift it, or if it's just shown being lifted.
I'll look back through my pictures and see if I can remember it more clearly.
Also, Discovery Place in Charlotte had some very nice levers in their mechanical exhibit area a few years ago - you might check there.

Hi, all -
If your institution (or an institution you know or have visited) has either of the following types of exhibits, would you please email me off-list ([log in to unmask]) to let me know?
1) A "giant pulley" exhibit - the kind where visitors sit on a series of chairs (usually 2 or 3), each of which has a pulley system of a different mechanical advantage (i.e., different numbers of pulleys/ropes), and try to pull themselves toward the ceiling using the pulley systems.
2) A "giant lever" exhibit - a) The first-class lever kind, in which a heavy load is placed on one end of the lever, and ropes of varying distance from the fulcrum are placed on the other OR b) The second(?)-class lever kind, in which the fulcrum is on the floor and 2 ropes are attached on a lever extending toward the ceiling at different distances from the fulcrum. (When I've seen visitors use this exhibit, it's often been as a "tug-of-war".)
Thanks,
Bill
