Make a Mechanical Arm

Make a collapsible grabber using an accordion linkage.

An accordion linkage is basically connected scissors. The scissor mechanism in itself is no more interesting than a lever but when they are connected, the chain reaction is remarkable.

Changing the size of the straws will reveal very quickly the limits of this mechanism. One way to strengthen your mechanism is by extruding the mechanism. Another more efficient way is to triangulate your structure.
