When I developed the Blasters I started to look at manual exercises and the way we do them in light of simple machines. Since the A-Stretch was based on the lever I started thinking about which other applications could benefit from this logic. One morning when I was wringing a towel out I thought of the screw and I applied this to the towel. With a few simple twists and pulls the towel got a bit longer. The more I did this the longer it got. The thing that amazed me was when the towel was twisted it took less force to accomplish this then if it was not twisted. It also gave me more confidence that the fabric would not rip due to the thicker, bundled state it was in. This related so much to basic penis stretching and I sat down right there and gave it a go. My penis had a much more intense stretch with much less force applied. I also noticed that I made instant, temporary, length gains.
