1/2 apple, 1 popsicle, 1 medium-sized plastic bags that seals

Natron Solution- 1/4 cup table salt, 1/2 cup sodium carbonate (powder bleach), 1/2 cup baking soda
 
 
 1. Make the Natron solution (recipe above) in the plastic bag.
 
    



 2.Carve a face into the apple with the popsicle stick then stick the popsicle stick into the apple so you have a handle.
 
   
 3. Dip the apple into the Natron Solution until the face is covered, and leave the apple in the bag.
 
   
 4. Leave the bag open in an upright position to allow air to flow. Record your observations as your apple mummifies.

 
 
The Natron Solution dries the apple just as it would dry a human body to make a mummy. By eliminating moisture, you have eliminated the source of decay. Natron is made up of four salts: sodium carbonate, sodium bicarbonate, sodium chloride, and sodium sulfate. The sodium carbonate works as a drying agent, drawing the water out of the body. At the same time the bicarbonate, when subjected to moisture, increases the pH that creates a hostile environment for bacteria.
