We knew the water would flow down the tube rather fast if it was at a continuous downward angle so we decided to take 25meters of the pipe and run it down the stairwell of the WT building next door to us. Apart from getting a few strange looks from passers by we managed to conduct a very important prototype because it told us approximately how long it would take for the water to flow from one end of the pipe to the other. Unfortunately, we realised that it would take about 30 seconds to travel down the entire pipe. Since we wanted to have 2 pipes on our project to allow the audience to play the instrument this meant we would have to cut that time in half as well. 15 seconds was not a lot of time. Hence we decided to spiral the pipe down the vertical section of the railing (top to bottom to ensure proper water flow) and then have the pipe going straight towards the top of the next vertical section. This decreased the angle of the pipe and slowed the water down a great deal giving us a lot more time in between each keyboard hack. This also created an amazing accident. We found that with the decrease in angle, it was a solid portion of water flowing down the tube. It flowed in bits and pieces. Which meant that the keyboard hacks would randomly turn on and off with small and large droplets of water that followed the main stream. This was perfect because it meant that the sound would never sound the same every time and generated a sense of 'randomness.'
