There's something entrancing and magical about this bubble-blowing machine. I love the idea of building a device that creates something so evanescent. I still remember when I used to go to a summer day camp in North Carolina's SciWorks -- then called the "Nature Science Center" -- and all the campers used to dip string in bins of soapy water and blow through them. So peaceful and yet so exciting.
