Hang them from a hook, give them a pull, and you have a wonderful demonstration of oscillation. Great for starting a discussion on such topics as periodic motion, frequency, potential and kinetic energy. Unlike some similar demonstrations, these critters are weighted just right and the springs have just the right tension. The result is movement that is slow and gentle enough that even young student can count the cycles. Older students can easily time them with a stopwatch. The springs and weights for each character are a little different giving them different properties. Having a variety allows you to make comparisons. Figures are about 15 cm (~6 inches) from head to toe. Springs stretch to about a meter (~39 inches) in normal use.
