Dear List,
I'm now THE committee for physics display case
demonstrations and displays at my University, and I'd like
your input on what makes an entertaining/pretty, or
educational/interesting display case demonstration
[preferably change the "or" to an "and", of course].
I do not yet know how many such cases I will be in charge
of, nor how large each might be, so space limitations may be
a big factor. Nor do I know if any of them will be viewable
from all angles. I also don't yet know what kind of power
draw limitations each might have (so something that requires
a joint recirculating water pump and dehumidifying system
might be overkill). On the other hand, I'll have access to
each display, so that if something requires periodic
maintenance, I can do it.
I suspect that everything from "Here's a lucite-encased
meteorite with explanation" display, to interactive chaotic
pendulum, to "look at this live barometric feed today and
come back tomorrow and compare reading and weather to today's
reading and weather", to "drinking bird" might be fine. With
some time I could even cobble together a large and imposing
and dangerous-looking Jacob's ladder. One which should be
easy and probably lots of fun would be to set up a microwave
doppler system which could detect people moving around the
display and give a nice oscilloscope display of their
relative movements.
So: What might draw the eye and the brain? What butterfly
wings might plant a seed of wonder in a small visiting
child's brain and make him think, years on, that perhaps this
science stuff isn't all that boring? What passive or active
demonstrations might *you* like to see done well, and what
would make them done well for a large range of viewers/users?
