How do you safely melt Styrofoam?

Will vinegar dissolve Styrofoam?
Vinegar and more specifically “weak acids” will not dissolve styrofoam (the frequently used designation for foamed cups etc.). Acids will soften the thin walls of the plastic bubbles that make up foamed polystyrene. The bubbles can collapse if the exposure amount and time is enough.
How do you crumble Styrofoam?
All you have to do is grind it up. Clear the area where you will be grinding. Put on old clothing. Set a wheel sander to a lower setting. Hold Styrofoam cups, packaging and containers against the spinning sanding wheel. Use pumice stone or sandpaper if you don’t have a wheel sander.
How do you cut foam without hot wire?
Bladed implements like knives, box cutters, precision blades (like X-acto knives) or hacksaws are great for cutting through styrofoam, especially if you don’t need to make any curved cuts. For a smoother cut, run the blade along an old candle before cutting your styrofoam.
What kind of wire do you use for a foam cutter?

Can you use a jigsaw to cut foam?
The S 155/W jigsaw blade is engineered to cut rigid foam and fiberglass insulation, cardboard, foam rubber, and similar materials up to 5 inches. Festool jigsaw blades are engineered for cutting efficiency, long life, and superior cutting results, with a universal T-shank design that fits most professional jigsaws.
Will rubbing alcohol dissolve Styrofoam?
So: polystyrene is inherently easier to dissolve in any solvent. Isopropanol will tend to dissolve hydrogen bonding solutes where acetone just doesn’t care about that.
What happens when you pour acetone on Styrofoam?
Styrofoam dissolves in acetone in a similar way to how sugar dissolves in water. It is a physical rather than a chemical reaction. The acetone splits up the long chain of molecules, and the air disappears, causing the volume to shrink radically.
Can I burn Styrofoam?
Burning Styrofoam, or polystyrene, is the least appropriate way to get rid of it for both people and the environment. Research has shown that when Styrofoam is burned it releases toxic chemicals and smoke that can damage the nervous system and lungs.
Will hot oil melt Styrofoam?
