just wondering can you use clear saran wrap instead of plexiglass/clear vinyl after reading this and talking to my mom she asked me this, also for heat pads she also asked about using those heating pads for aches and pains like a Sunbeam 756-500 Heating Pad that comes with heat control of course i know it won't be an auto shut off if it reached a certain temp and have to monitor temps alot

thank you
