Moving into a new neighbourhood in the Southern Highlands has found the yard a veritable highway for the neighbourhood ‘Toms’, some of these brutes wont take mothers kindly “shoo cat! shoo!” for an answer.
Taking things into my own hands I decided to pull the top off an empty dry powder fire extinguisher and fill it with water. All you need to do then is recompress it with air from a common compressor with one of those blow-down guns on the end of the hose. You just force the air back through the nozzel end of the extinguisher, it pushes past the trigger and stays in the bottle.
Then you have one of these!
