Mathematics and Art - Experimentation for Accuracy

So now, with another session free for experimentation with my mum out of the kitchen and watching tv, I set out to move fast and quick. this time, I used to same measuring jug, but also got out 8 of the same glass cups. They weren't too small and they weren't too big so I guess it was just right in my opinion. So I decided to work at this myself before using the sources I researched earlier to see if I could do it myself.



So working in 40 ml increments I had one large jug to hold the water with a smaller measuring cup that measured 40 ml, 80 ml, 120 ml, and 160 ml. So of course, working in 40 ml increments was the smartest choice. I filled up to 40 and poured into the large jug. Then from the large jug into the glass cup for greater accuracy as the jug also had measurements present. Accounting for the fact that every time I swapped jugs or cups some water would remain in the previous cup or jug so I was always fill the water a bit past the 40 ml mark. So with this I had 8 cups in 40 ml increments. 40, 80, 120, 160, 200, 240, 280 and 320. I played these in order to notice that there was indeed a change.

But it didn't seem to match the scale that I had hoped for but with this I had confirmed that the size of the container would play a part so my next idea was to play this with fractions. So each glass container would hold water equivalent the a designated fraction of the entire container as recommended on one of my read sources below.
