“When you mix Styrofoam (extruded polystyrene) with gasoline, the Styrofoam breaks down. All the air inside escapes, and it becomes a wet, gooey mess. If left out to dry, it gets hard again, but not like before, without the air – it resembels plastic.”Click to see full answer. People also ask, what does gasoline and Styrofoam make?Yes. The resulting, sticky and gelatinous material, is effectively home made “napalm”. It can be be made by dissolving pieces of Styrofoam in gasoline or diesel fuel to form a flammable jelly-like substance. A modern version, napalm-B, is now thickened using styrene derivatives.Subsequently, question is, does Styrofoam go off gas? fresh polystyrene contains residual pentane and if large amounts of EPS materials are stored in a confined, unventilated area such as a semi-trailer truck, pentane may off-gas and create measurable airborne concentrations. Beside above, what happens when you mix acetone and Styrofoam? The air in the foam leaves, and because Styrofoam consists mainly of air, when it dissolves in acetone it completely loses its structure. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically.Can you really make napalm with gasoline and orange juice concentrate?The three ways to make napalm: One, you can mix equal parts of gasoline and frozen orange juice concentrate. Two, you can mix equal parts of gasoline and diet cola. The napalm is originally called napalm because is mixture of naphthenic acid and palmitic acid.
