The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead. Natron is made up primarily of sodium carbonate (a very efficient, but relatively expensive, dehydrating material), with about 17% sodium bicarbonate (baking soda). This activity explains how to create your own fish mummy using common baking soda!
