how do we make a transparent plastic sheet translucent?or vice versa
My only guess is to heat it until the plastic thins enough to become translucent. Of course i have no clue how you might go the other way with it.
translucent, opaque, translucent, opaque, translucent, opaque,sparkling if it hasn't have been given many air bubbles, sparkling close to sufficient, sparkling, translucent in that order.
Rub the transparent sheet with fine sandpaper. Vice versa - polish it with successively finer grades of polish.
To make a transparent sheet translucent, you just need to roughen up the surface (e.g. with sandpaper) so that light is scattered, rather than being transmitted uniformly. To make a translucent sheet transparent, you need to polish the surface smooth. Have you ever tried putting a drop of cooking oil on to a piece of tracing paper? The oil spreads and fills in some of the surface irregularities, creating a surface which goes some way to making the sheet transparent.
