Dilutions From A Dissolved Crystal

My aim was to do the experiment correctly

 what we needed was a test tube rack 6 test tubes a tiny crystal most likely purple so you can see it best a syringe and a measuring cylinder

In science today me and my friends did an experiment. In the experiment we dissolved a tiny crystal in water. The crystal made the water turn purple we filled the first one with 10 litres of water and the others with 5 litres the way we measure was with a measuring cylinder.

we put the crystal in the first one and we shook it for about 2 minutes then we used a syringe to pick up 5 and put it in the next one then we shook the tube for five seconds then we repeated what we did in the second tube with to all the others.
