The volunteer is smiling, because he’s thinking about the twenty dollars he’s going to get – after the experiment is over.




In an earlier version of this creation, the two hoses connected to the back of the booth. One hose had a darker connection than the other. Phillip liked that, saying that it looked like one was for input and the other for output. Later, when I changed the hoses to the upper mechanism, I used the same color for both. Phillip said he missed the output/input effect. It wasn’t until I was working with the photos for this post, a few minutes ago, that I realized I had forgotten to change the hose colors. Sorry about that.
