Place the pebbles, gravel or marbles into the bottom piece of the bottle.
Take the top pierce of the bottle, turn it upside down and place it inside the bottom pierce of the bottle. Make sure there is no cap attached.
Line up the cut edges and tape them together so the top piece is held firmly in place.
Cut enough tape to run from the top of the bottle to the bottle and stick it down.
Line up the ruler against the tape and draw a small mark just above the pebbles. This will be a measurement .
Continue marking in mm or cm measurements up the side of the tape.
Place the bottle on a level surface and pour water through the top until it reaches zero.
