<blockquote><b>Quoting Nathaniel'sMom:</b>" It's not bleeding yet because the horn is blocking the hole. It's pretty much the same thing as filling ... [snip!] ... through it. If you keep the pencil in it there is no water leaking out. As soon as you remove the pencil the water pours out."</blockquote>
Hm yeah that does make sense. Plus the horn is thinner at the tip and gradually gets larger so that would act like a plug.
