How Strong? - Procedure
Remove the lid of a milk jug and make a small hole in the lid.
Place the plastic funnel in this hole and put the lid back onto the milk jug.
Cut a piece of nylon line (approximately 1 foot).
Wrap one end of the nylon line around a popsicle stick 3 times and secure with masking tape.
Repeat this with the other end of the nylon line.
Assemble the ring stand with an arm (please see picture).
Clamp one end of the nylon that has been wound around the Popsicle stick with one of the
clamps and place on the arm of the ring stand.
Clamp the other end of the nylon line and the milk jug together with the other clamp. This
end should swing freely. Be sure to have about 5 inches between the milk jug and the table
top.
Place water in the milk jug through the funnel until the nylon string breaks.
Weigh the clamp, milk jug, and water using a sensitive bathroom scale.
