Measuring Out Your Liquid
There is a specific way to measure a Test Tube. If looking at it from the wrong
angle, your measurement will be off.
To get the right angle, place your eyes parallel with the line of the liquid in the tube
and at the same level.
There is a slight curve in the liquid set in this tube. This is normal. Measure from
the bottom of that curve.
