No trip to Israel would be complete without a visit to the Dead Sea. As well as being the lowest place on earth, it is also one of the world's saltiest bodies of water. (It's almost 10 times saltier than the ocean!) The high mineral content of the water (and mud) makes it a desirable health and beauty product. You can actually scoop up salt from under the water the way you might with sand at the beach. The salt also crystallizes on rocks along the shore creating really neat designs and formations.
