广播电视英语短句 第 290 课：找到粘土-6

You can also perform a test. 你也可以做一个实验。

Take some of the material and add enough water to it to make it seem like you are making bread. 像制作面包一样，你可以把一些材料和水添加进粘土里。

Then press it in your hand until it is about the size of an egg. 然后用你的双手紧压它，直到它形成一个类似鸡蛋的样子。

It is probably clay if it holds together instead of falling apart when you stop pressing. 当你停止紧压时如果它仍旧紧紧地结合在一起而不是逐渐散开，那就表明它可能就是粘土了。
