you dumb boy!!
Plastic foam is generally a better insulator than wrap because it has a higher R-value, which measures the material's resistance to heat flow. Foam insulation can provide better thermal performance and help reduce energy costs more effectively than wrap.
Foam wrap reduces radiation by reflecting heat away from the object and by providing an insulating layer that traps heat. It reduces conduction by creating a barrier between the object and whatever it is in contact with, slowing down the transfer of heat through direct contact.
Well, you could try those Styrofoam "chips" used as packaging in shipping and strips/squares of bubble wrap.

to stop condesation of water from the surface of pipe.
Usually the wrap iss installed first. Rigid foam insulation is often installed outside the building wrap, and batt insulation is always installed inside the building wrap. This is because batt insulation is much more moisture absorbent than most rigid foam so needs to be protected from external moisture. So batt insulation will not be installed until after the building wrap is in place to protect it, and externally installed rigid foams are not fixed in place until after the wrap is in place because they are fixed over it.
To protect your suitcase with foam during travel, you can purchase foam padding or foam sheets to wrap around your belongings inside the suitcase. Make sure to securely fasten the foam around your items to prevent shifting during transit. Additionally, consider using a hard-shell suitcase for added protection.
Some creative ways to wrap furniture for protection during a move include using blankets or towels, bubble wrap, plastic wrap, or furniture pads. You can also use cardboard or foam boards to provide extra cushioning. Additionally, using stretch wrap or shrink wrap can help secure the wrapping in place.
You will want to use a shipping container that has bubble wrap and a stiff exterior. Many laptops are shipped in cardboard with bubble wrap and foam interiors to prevent damage.
You basically need a hot wire. There is lots of info available on Google. Here is one URL with instructions for a home made foam cutter. http://www.instructables.com/id/Hot-wire-foam-cutter
Well you could get some foam and wrap it in duct tape if you wanted to, but I would just reccOmmend buying a basketball.
Packaging foam is used in shipping to make sure the item inside doesn't loosely move around in the shipping box and break. Many times bubble wrap is also used for extra security.
