From the parts that build up the string popsicle climber (back, arms and legs) only the legs are mobile, due to the rubber band. The forces acting on the climber, the following is observed: The climber's weight is compensated by the friction between the arms and the string (Hot glue & toothpick). When the string is pulled, the toothpicks straighten the legs. This causes the body to stretch, when the string is tense, resulting in a small rise in the body. As soon as the pressure on the string is released, the arms provides enough friction for the climber to hold on to the string while the legs are lifted by the rubber band, moving the string to a new position. Awesome science.
