		<description>&lt;p&gt;Pour &lt;a href='http://www.owl-ge.ch/spip.php?article1409' class='spip_in'&gt;transvaser un liquide&lt;/a&gt; d'un r&#233;cipient dans un autre, on plonge un tube de verre verticalement dans le liquide jusqu'au fond du premier r&#233;cipient rempli. On laisse p&#233;n&#233;trer le liquide &#224; l'int&#233;rieur du tube puis on ferme l'orifice sup&#233;rieur du tube. On d&#233;place ensuite le tube au-dessus de l'autre r&#233;cipient et on lib&#232;re l'orifice, laissant ainsi le liquide s'&#233;chapper du tube et tomber dans le second r&#233;cipient.&lt;/p&gt;
