dum

Now, at the moment, I've got the same sort of amount of pingpong balls hitting that hand as I have that hand, so I'm not pushed anywhere, but if I remove half the air molecules from this side, suddenly dum, dum, dum, dum, dum, dum, dum i start moving.

现在 我的左手和右手两侧 有相同数量的乒乓球 所以我一动不动 但是如果我把这边的一半分子抽走 突然间 我开始移动了

Well, you've got to imagine the air is made up of invisibly *all molecules, like little pingpong balls whizzing around and they dum, dum, dum knock into things.

想象一下 空气是由不可见的小分子构成的 就像小乒乓球在高速运动 它们不停地撞击到物体上

Dum spiro spero while there is breath, there is hope.

"一息尚存就有希望" 只要还有呼吸 就仍有希望

It's got a lid because it's known as a dum pukht pie.

因为这是杜姆帕克特派 所以上盖派皮
