redneck style:
needed:
- empty oil drum
- air compressor
- adapter to connect air compressor to oil drum
- adapter to connect oil drum to tire filling hose (both at the same time)
steps:
1. put washer fluid in empty oil barrel
2. attach the above mentioned hoses, and make sure that the air hose from the compressor is higher than the exit to tire filling hose. also make sure that the fluid level of the washer fluid is above the attachment port for the tire filing hose.
3. attach the filling hose to the tire
4. start blowing a gentle bit of air into the oil drum. The pressure in the drum will force out the water into the tire, because the exit opening is below the washer fluid level.
Now dont be too hasty at step #4 as oil drums start to deform at about 1.5 atmospheric pressure. I havent been in the opportunity to discover at what pressure they burst.
