Dungeon Defenders
Eternian Greatsword

This sword was made using PVC pipe and foamcore board. I made an inner core to the sword to which I mounted a string of blue LED rice lights. (The battery pack was in the handle of the sword.) I coated the exterior of the sword with translucent plastic (which had been bent to look like a solid blade made of crystal.) I placed a press on LED light in the base of the sword (which was connected via velcro so it could be taken off and batteries replaced.)
