Star Wars Ultimate Force Lightsaber
Activate the lightsaber with a press of a button and it’ll light up from handle to tip with that well known noise. Motion sensors in the handle detect when you’re swinging it from side to side, and complement your mad skills with sound effects.
Make contact with an object and it’ll even make the well known electric snap-crackle. When you’ve dispensed enough justice for one day, press the same button on the handle and it’ll power down from tip to handle, just like the real thing.
