A realistic DIY handheld mechanical gadget made from simple household materials. The device uses a wooden ruler as a handle, held vertically. A yellow pencil runs parallel along the ruler and can slide up and down, guided by two loose rubber bands wrapped around the ruler. At the top of the pencil is a small paper cutout shaped like a hand. Near the bottom of the ruler is a small round plastic button positioned underneath the pencil, acting as a trigger that pushes the pencil upward when pressed. A rubber band is attached from the top of the ruler to the pencil, creating tension to pull the pencil back down. The scene is on a desk with scissors nearby, slightly messy, showing a homemade prototype. Natural lighting, highly realistic, clear focus on the mechanical structure. Mehr sehen
