Discovering how this wonderful sense works. Sound is really a vibration, a movement. When something moves, it cause a sound wave (which works in the same way as rippling water as seen in the picture of Javier, Ryan, and Daniel). It was so cool to see that the salt "danced" when the music played (-picture of group around the stereo). We had fun having whispered conversations through a long tube. Normally, a whisper can only be heard by people directly near you. But through the tube it gets louder because the weak sound waves (whisper) doesn't get lost and end at a short distance as it should. Instead, it gets squashed into a small space which causes it to build up and conserve its "energy" so that by the time it reaches the end, its louder than at the beginning. No one was able to hear what was being said besides for the person who had his/her ear to the tube. We also enjoyed talking through a rube with a paper secured to it. We were able to feel the vibrations that were being made.
