Inquiry (采购产品): Plastic Spheres I am looking for hollow plastic spheres that are clear and 38 mm (1.5") in diameter. I use these for teaching students about crystal structures. I plan to glue these together into hexagonal sheets for stacking for iionic crystal moderls. I have some in our teaching collection, but I do not know where they aere purchased. Do you have any such products or information about where I might purchase them. **** Hidden Message ***** Thoams Sharp Bateman Physical Sciences Bldg.
