You show a transparent tube completely empty, you can even take the wrap around the tube away to show everything is empty and fair. You wrap the black piece around the tube again and after a snap in the fingers or magical spell you can now produce sponge balls, silks, etc. The tube measures approx 19 x 6 x 6 and is professionally made of acrylic. Use your own production-materials (we use a Silk 60 x 60 cm) in our video.
