Large pipe cannon that uses high pressure air to launch a potato hard enough to knock a hole in a wall. You never made one?
No......but heres a good story. They had a elementary school fair when i was a kid. well they had those rubber hose sling shots (the ones that you have two people hold....and then pull back. Well.....they were putting water ballons in them....and having the kids shoot the balloons over the portable teaching units. At my young age, i was the first to decide to shoot it right at the cottage. Kids were cheering me on and the adults holding the tubing were cheering as well. The balloons were going fast enough to put dents in the cottage. None of these adults had the sense of mind to stop that practice. One hour later and a completely dented cottage later, one of the school officials shut down that activity.
