Maybe no one else is interested but if you find time to try that ... I personally would very much like to know ... at what pressure-volume threshold ... could get us to move around the car wash (drain below us) in an elevated state with the gun in a McGyver Style backpack like harness.
Now that would really impress our customers IMHO! Finally the futuristic Jetsons cartoon becomes real life??? Be sure & repost when you git er dun!!! Adding a video of it from your smart phone would be even more fantastic!
