Build your own electronic hot wire knife from a kit at home.

The hot wire knife uses an electric current carried through copper tape to heat up a wire which then can cut through styrofoam by melting it away.

This product is used to help teach how electricity works, and used as a fun make-at-home project. Once it is built, it can also be used for more home projects, like styrofoam puzzles, ornaments, moulds, etc.

The hot wire knife kit comes with

• wooden parts cut with a laser cutter
• two C batteries
• a screw and nut
• copper tape
• wire

This is everything that is needed to complete the project. There is an instructional video that should be used to build the knife hosted on Youtube.
