This is a great Routine with a lot of opportunity for patter and comedy, and at the same time, teach the audience the importance of traffic lights. This effect works similar to the mismade flag effect. You have a traffic light post with no lights on it. You take a red , yellow, and green silk and place them in a magic bag. When the traffic light is taken out of the bag, it comes out with just two lights. You put it back in the bag and with some magic, it comes out with all the three lights. Great for a school, library, or a birthday show. Comes with 3 traffic light silks. The traffic light silks measure about 9"x 9". Solid colored silks are sold separately.
