The world's oldest, organic powered airbrush:
Take a soda straw and place a horizontal cut, 3/4 of the way through the straw, at about the middle of the straw, bend the straw at this cut so that you have an "L". Dip one end into your colour and gently blow on the other end. By blowing you are creating a vacuum on the bottom half which draws up the colour, and then "mists" when it comes to the cut. Many old fashioned spray guns were based on this principle.
Experiment with different soda straws, cuts, and pressures when blowing
