This is a rubber band powered bow and arrow. An additional file for spare arrows are also provided.
Just use a regular small household rubber band (tested with a rubber band approx. 37mm round x 2.0mm x 1.0mm thick) and install as shown in the images.
WARNING: Depending on the rubber band installed this small bow can shoot the arrow 5 metres or more. Have fun with it but take care when shooting around people. Do not aim towards anyone's face.
