"A top-down technical drawing and 3D sketch of a Rube Goldberg machine on a small wooden table with a U-shaped layout. The path starts in the back-left corner with a cardboard ramp (inclined plane) holding a tape roll. At the bottom of the ramp, along the back edge, is a toy car (wheel and axle). In the back-right corner, the car hits a ruler (lever) balanced on a glass jar with a screw-on lid (screw). A string is tied to the ruler and draped over a chair back sitting next to the table (pulley), connected to a juice box on the side edge. A second string runs from the juice box to a toy car with a thumbtack (wedge) at the front. The final goal is a large balloon taped down in the front-left corner. Use arrows to show the U-shaped flow of motion from corner to corner." Ver mais
