Sound Experiment 2: Marie

Today, I tried doing the Cymatics experiment again. (You can view my first attempt here.) This time, with my sister, Marie, as my voice subject. I took videos! So you can see how the experiment works. And also so you'll see why I need someone with a bit more voice training.

Marie: "I feel bad that I don't have a very nice voice."
Me: "That's alright. We're still producing... Stuff."
Marie: "I wonder if my sarcasm has a particular shape."
