There were bouncy balls and plastic bugs and those little green stars that everybody stuck on their ceilings.

有弹性球和塑料虫子，还有每个人都粘在天花板上的绿色小星星。

We're going to use bouncy balls, but you can use marbles, or even foods like nuts or sunflower seeds.

我们将使用弹力球， 但您可以使用弹珠，甚至是坚果或葵花籽等食物。

That's what these bouncy balls are for — or whatever you're using as your small, round objects, like nuts or seeds.

这就是这些弹力球的用途——或者任何你用作小的圆形物体的东西，比如坚果或种子。
