How do I make a device to shoot or propel water balloons (that dont kill people!) from a mounted Position?
Because i Have made a treehouse and want something to put on it that fires water balloons on a swivell or hinge of some sort
I have seen Some things like waterzookas that shot at 500 miles per hour
But that hurts SOOOOO
Also it needs to be able to be both of the following
able to be fully functioned by on person
accurate for at least 30ft
weather proof or resistant
