while looking for science fair projects, i came across this, and am considering trying out the experiment:
"I Did a project to dentermine if the processing of food produces gas. I took the fresh, canned, and frozen veggies and grounded them up and mixed each with vinegar, put them in test tubes and placed a balloon over the tube and measured the gas in the balloon. This won first place in the school and regional science fairs. "
my question: how would you measure how much gas there is in the balloon?

You could weigh each of the balloons, but first see how much a each balloons weighs and subtract it. For example, if each balloon weighs 1g, and a balloon with gas weighs 3g, then there are 2g of gas because 3 - 1 = 2.

put a pressure gauge on a pipet between the test tube and balloon
or measure them in size in relation to a control, example balloon b is twice as big as a so it has twice the gas

By how inflated it is, provided they are all giving off the same gas :-)
