Abstract
Some designs of simple wave demonstration devices have been described in this journal and elsewhere.1–5 A new simple model can be built using only dowels, binder clips, and loops of thread. Not only can it be easily assembled, stored, or disassembled, but also all the students in a class can cooperate in its building by connecting successive pieces (units), which make the apparatus as long as desired.
