For appearance, "Remix" made up of many materials such as woods, acrylic, aluminum, pumps and "Water". One thing we knew that this project is going on, controlling water is more difficult than we've thought. So, what it does is there are 10 switches in each water pillar and each switch has own musical instrument. Once users push FSR, water is flowed from one pillar to the other by water pump and then triggers switches to play music.
