| | |  |  | 천연탄산소다 용해제를 만들어 사과를 그 안에 넣어 관찰하며 고대 이집트인들이 미이라를 만든 원리를 이해한다. | |
|  | | |  |  | 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.
- 천연탄산소다 용해제는 사람의 몸을 미이라로 만드는 것 처럼 사과를 말린다. 천연탄산소다는 탄산나트륨, 중탄산소다, 염화나트륨, 황산나트륨으로 구성되어 있다. | |
