There&#x27;s a very simple explanation for why anything that floats wouldn&#x27;t ever appear in the lake, even though the Kettle drains to it:<p><pre><code>    | | Kettle
    | |
    |~|    |~~~~ Lake
    | |____|
    |___________
</code></pre>
The water level would equalize between the Kettle and the Lake, but there&#x27;s no way for anything that floats to get over.
