This neon light up wire with a battery pack is so much fun to play with! I have so many ideas of what I am going to do with it.. Make a picture frame that lights up. make fake flames that light up for my fake fire place we hang on the wall for Christmas so Santa can get down the chimney! I am going to make a neon open sign and a closed sign for our bathroom.. So many ideas.. The possibilities are endless! It works on batteries so there is no danger from electrical wires! Gives off a beautiful glow when lit! Such fun!
