i guess according to me cellophane is animpermeable membrne which infact means water cannot pass through it from a higher cocentration to a lower one do consultlower secondary science book 2 hi to every one from fatima.... :)
You can get cellophane at most Craft Stores, try: <michaels.com> <hobby lobby.com>
Cellophane is a thin, transparent sheet made of regenerated cellulose
Cellophane is made from plant matter [cellulose]. It presently can't be recycled but it does decompose in 30 to 90 days in a composite pile.
No sand is quiet permeable meaning water can flow through it.
