Its not a joke.
Extinguishers are not fun.
They are serious.
Using an extinguisher to paint a wall is an act of pure anti-social behavior.
So is telling someone how to do it.
Step 1: Get a Fire Extinguisher
Step 2: Empty your Extinguisher
Step 3: Fill the Extinguisher
Step 4: Pressurize the Extinguisher
Step 5: Paint with your Extinguisher
TIPS: using different ratios of paint, water, and air will result in different types of spray,
more paint and water, and less air will give a thinner line.
More air than paint and water will result in a larger spray but will run out of paint very fast.
