例如，我不认为二手碗或衣服是可以接受的，因为不一定干净。

For example, I don't think second-hand bowls or clothes are accepted because it is not clean enough.

在下个阶段进行之前，你要先确认你所使用的碗和你的手是完全干燥的，否则沐浴弹遇水会起反应冒泡。

For the next stage you need to make sure that the bowl you are using, and your hands, are completely dry - otherwise the bomb will start fizzing.
