Condoms seem to be very popular for emergency water carrying. They do seem to have some ++++, sealed package and small in size. I carry a small oven cooking bag. The kind that look like a zip lock without the seal. They are somewhat larger than a condom, but I have put one quart of water in one, tied it close and tossed it in the air. It landed intact. Their ruggedness might come in handy, and they should have multiple uses. They come four or five to a box and are relatively inexpensive. <br><br>Regards<br>Bruce Geissen<br>Texas <br><br>
