*****************************************************************************
For exhibits we have used several alternates to sand from walnut shells to
micro beads. We have also used some finely ground rubber mulch.
To keep things from tracking off we have used industrial mats from C and H.
These heavy duty mats removed most of the material or contained it to an
area.
I will try to look up some sources for the alternate sand materials tomorrow
at work.

I've searched the archive and couldn't find any first hand account from a
centre that uses an alternative to sand.
We'd like to create a discovery table where kids (5-10) can play with
flowing
properties, measuring and volume but water is not an option.
Has anyone used plastic pellets or other sand alternative with toys like
sand
mills, and clear acrylic measuring cups? What sanitizing/cleaning methods
do
you use? Is scratching a problem? What's the trackability like from the play
area? Do you use catch mats or just regular vaccumming?
Sources for the pellets would be appreciated too. The only one I have is
from
Spectrum; 4.5kg for $36
Thanks.
