เรื่องย่อ
Big Machines have always fascinated young children. This DVD contains simple, discovery-filled reports about Big Machines. Here, children have time to calmly see how the machine works and what it does. Among other things, we see big machines that work in ports, mines, airports and on farms. The machines roll, dig, lift, shovel, drag, extinguish and empty. Exciting!
