Introduction

Convert any plastic bottle or transparent cup into a volume measuring device by using a fixed volume device like a syringe or ink filler.

    • Exercise caution when using the scissor.

    • There is no need to use the needle with syringe.

    • Do not play with the needle.

  1. Cut a strip of paper equal to the height of the bottle.
    • Cut a strip of paper equal to the height of the bottle.

    • Using glue, stick the paper strip along the bottle's wall.

    • Stick the paper from the base of the bottle to the top

    • The length of the strip should be just enough so that you can mark the volume scale along the strip

    • Using a 5ml syringe, pour 20 ml of water into the bottle i.e. fill and empty the syringe 4 times into the bottle.

    • If you are using a 3 ml dropper or 3 ml syringe, you need to fill and empty full dropper 6 times and 2 ml once.

    • Now that you have the 20 ml level on the bottle, mark the level on the strip and label it as '20 ml'

    • Likewise, repeat the above steps and mark the paper strip at regular intervals (20 ml, 40 ml, 60 ml, 80 ml, 100 ml)

    • This is your volume measuring cylinder which can measure volume in multiples of 20 ml within the range of 0 ml to 100 ml. You can change the range and also measure in multiples of 10 ml or 5 ml if needed.

    • Empty the water from the bottle once you have completed the scale

    • Cover the paper with a transparent cellophane tape to have a water proof volume measuring scale!

    • One needs to be diligent while measuring the unit volume with the syringe (or dropper). Even 1 ml error in each filling would multiply to 5 ml when the full 20 ml is marked.

    • The cylinder is not placed on a flat surface while marking.

    • Use bigger syringes to mark the volume scale along bigger containers/bottles
