Have anyone seen that episode, where they use a hose, which is coming down from a hill... with lots of water in it ? Total length of the firehose was about 750m.
The pressure in the end of the hose was ''quite'' acceptable , around 10 Bars.

anyway... this might be a challenge for our little SPUD community to replicate the results.
Have a look at the video, then you'll get a glince of the ''REAL SPUDGUN''
