ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

I hope someone can help.
We have a small wind tunnel with shapes that fit on a sled in the
test section. We have used styrofoam for the shapes, but they don't
last very long. We tried coating the styrofoam with foam coat, which
helped extend their life, but they are still getting really beat up.
I was wondering if anyone else has a similar exhibit or any
suggestion on what material we can use for durable, lightweight
shapes. Does balsa wood hold up?
Thanks,
Anna
