Mummy Magic

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.
