Hi All,

Does anyone have any experience with a cart-type demo that shows the
effects of dehydration -namely shrinking and/or shrivelling?  Or know of a
material that expands when it gets wet, but can be squeezed dry down to a
much smaller size and will retain that smaller size and shape when dry
until expanding again when wet?  Any ideas or suggestions would be
welcome!

Thanks,
Maya Wade
