Washer tube and a glass bottle.

1) Take the washer tube that's on your car if you have no spare.
2) Buy some Fosters Gold™ if you don't have a glass bottle. Drink the contents first.
3) Place some brake fluid in the bottle.

4) Open the bleed nipple and watch the air come through the tube, gravity fed.

Always do rear first, furthest to travel from the mc.

5) Drink the remaining bottles from the 6 pack.
