1-3 可變重心棒(Center of gravity paradox)

說明：

CENCO Center of Gravity Paradox

A Fun Way to Demonstrate Stability

Show that things are't always what they seem with this captivating puzzle. Students will expect that a lower center of gravity will increase stability. Watch what happens!Balance this 120cm rod with its weighted end on a fingertip, and it totters and falls. Balance it with the weighted on top, and  it becomes more stable.

       由此儀器顯示出很多東西並不總是他們看起來的樣子。學生會覺得

        低一點的重心位置會增加穩定度。看看發生了什麼！以你的指尖將

        這根120公分長之棒子重端朝下並平衡之，他會搖晃並且掉下。然

        後將重端朝上平衡之，會發現它變的穩定多了。
