To prove it 验证

Someone asked a little boy: "Is a pound of lead heavier than a pound of feathers?" The boy quickly replied: "Of course it is."
 
When he was told "You are wrong. They both weigh the same," he insisted that a pound of lead is the heavier. He said: "To prove it, I would go up on the balcony and drop a pound of feathers on your head and then drop a pound of lead to let you say which is the heavier."
 
有人问一个小男孩:“一磅铅比一磅羽毛重些吗?”男孩马上回答说:“当然是。”
 
这人对他说:“你错了,两样东西重量是相同的。”但是男孩还是坚持认为一磅铅重一些。他说:“为了证明这一点,我会到阳台上去把一磅羽毛扔到你头上,然后扔下一磅铅,再让你说那样重谢吧!”
