Greetings,

We have a Gravity Well (aka Coin Vortex) and our deluxe bi-directional
coin slide has broken.  Actually it's just the backing plate that's
broken; the material is less brittle than acrylic but more rigid than
PVC board.  Can anyone out there specify the flavor of plastic for me,
and/or refer me to a current supplier for this exhibit?  (We got ours
from the Museum of Scientific Discovery in Harrisburg, PA back in 1998,
apparently now defunct).

Thanks,

Don Marvel
