Give the kids or even yourself a great new innovative way to learn about gravity and producing music at the same time. Yes, as you build with the Quadrilla Music Melody Composer, you will be creating your own music. What is this gadget? Well, it is a rollercoaster-esque building that you build. However, as you build the marble run you slip in five tone blocks under five section drop cubes, which creates music. The way you build your run determines how fast and in what order the tones are played. You can put in multiple marbles at varied intervals and get a nice beat going as they fall through your Quadrilla Music Melody Composer.
