“What Are The Five Properties Of Acrylic?”
“I don't know what the main 5 are but I hope this will help: • Excellent resistance to Mineral Oils • Good resistance to Dilute Acids, Aldehydes and Aliphatic Hydrocarbons • Limited resistance to Bases • Poor resistance • Poor resistance with Concentrated Acids, Alcohols, Esters, Aromatic and Halogenated Hydrocarbons, Ketones, Vegetable Oils and Oxidizing Agents. • Acrylic has a high degree of transparency. It is resistant to inorganic acids and alkalis but is attacked by a wide range of organic solvents. • Machineable and heat-bendable • Dries quickly • Attractive • Tough • Durable • Soft enough to work with standard hand and machine tools • Reasonably priced • Widely available. • It can be scratched easily.”

“Why Do We Need Bones And What Are They For?”
“We have bones to keep us straight. If we didn't have bones we would be like jelly. We wouldn't be able to stand up or sit up. Our organs would move around our body as there would be no rib cage to keep them in place.”
