A little about this puzzle

In a science demonstration hall, a pair of mechanical wings rests on a two-column test stand with a grounded base. Visible hinges and actuators connect the folding outer wings. An adult uses a handheld controller outside the exclusion area, leaving the other hand free; spectators stay behind a rail. Inspection and service tools occupy the front bench, stand perimeter, control position and rear rack. The color page presents the full scene, the outline page provides searching and coloring space, and the answer page colors the intended targets and matching key icons. Chinese and English editions share the same artwork. ## Image descriptions Choose the Color or Line art image, use the picture clues to find each object, and keep the Answer key separate until you are ready to check. The three images can be printed or saved as PDF using your browser.
