A suggestion on the home-made manometer, is to mark the U on one side in half-inch
increments, but number each as a whole inch. And I put green food coloring in the
water to make it easier to see. And easier to stain everything when it sometimes blows
out the other end when the gas is turned on :(.
Worked for me.
