Jackie,  Back in the day I worked with a guy whose family manufactured caskets.  They had a contract with the military and every one of them had to be waterproof.<br /><br />His job as a teenager was to get in each one, be closed in, and then it was immersed in in water while he checked for leaks inside using a flashlight. <img src="http://www.cruisecrazies.com/community/images/forum/tr-emoticons/ohmy.gif" style="vertical-align:middle" emoid=":ohmy:" border="0" alt="ohmy.gif" /> <br /><br />That does not sound like a job you would be interested it. <img src="http://www.cruisecrazies.com/community/images/forum/tr-emoticons/unsure.gif" style="vertical-align:middle" emoid=":unsure:" border="0" alt="unsure.gif" /> <br /><br /><img src="http://i386.photobucket.com/albums/oo305/kazphoto/Nursing/medical_equipment_cooling.jpg" border="0" class="linked-image" />
