h20 defensive applicator

Hmm thinking a little about car defensive systems ahem.. It would need a source of water, a delivery system and a method of propulsion.

Ideally it would be roof mountable and be able to swivel for at least 140 degrees. Something with a largish tank and would fire by a trigger pull. propulsion would be by pump, gas, pressure, gravity etc. twin barrels would be nice. So would a perspex screen shield or similar.

So we have 12v in the car
so we can look at windscreen motors, pond pumps, fish tank pumps, drill pumps

Or we could manually pump into store
garden spray units, empty polythene water holders

or gas CO2 probably
any sort we can get water displacement with !

Perspex shield might be tricky, but not impossible.

water tank could be anything pressurised or not, but most likely plastic....

trigger(s) probably best to get prefabricated.

Mixing electrical power and water usually not a good ideal

Not so much a water cannon, more a water base retaliation method..
