A long wire mounted in a vertical stand has a weight hanger on one end and a small platform partway down on which a pivoting mirror sits. Add weights to the weight hanger and the wire stretches, pivoting the mirror and deflecting a laser beam. The spot on the wall moves farther with each added weight.
Add weights in 2 kg increments up to 6 kg. Make sure that there is enough space between the apparatus and the wall so that the deflection is visible.
