A Mattel Hoverboard, great for evading obnoxious blowhards, as Michael J. Fox does in "Back to the Future Part II." The wood prop has the complete fully functional and rear ballbearing-mounted footpad that rotates 360 degrees, as well as the bottom "magnet plates." The hole in the top is where the handlebars were attached ($30,000–$50,000).
