Accurate Water measurements

Our measuring of water fill on launch days are not as accurate as they should be, they are probably with 50ml at best. Easy solution to this was to get a 1.5L bottle and mark on it the exact water levels for different water volumes. Having accurate scales makes this much easier.

First put the empty bottle and funnel onto the scales and reset to zero. This negates the weight of the bottle and funnel so that the scales will only show water added to the bottle. Pour in the water to the desired levels and mark off on the bottle.

We usually use 700ml and 800ml for our 2.5L rocket so we marked these plus a couple of others.
