Contour Surface Sanding
Another highlight. Keep this tight; visitors should grasp it in a few seconds.
Research is Fun: Dr. Caine tried this demonstration on a 3D printed contour surface. The friction from
the sander generated so much heat that the surface melted and the sander's head became perminately embedded in it.

3D Surface Pipecleaner Models
We put together this activity to help students explore using traces to understand three-dimensional surfaces.
Each pipecleaner is a trace of the surface, and students can compare these to their corresponding equations. This gives students
a hands-on way to interact with three-dimensional equations
Research is Fun: Student Sylvia Wagner asked her siblings (ages 18 and 9) to test this activity, and they did it much faster than she did!
