This allows you to get some graphing practice in if you desire, or just use it as a touchpoint to talk about the rate of drying. If you weigh your hot dog mummy each time you change the natron you can start to see how much water is being absorbed by the salt each week. Weigh your hot dogĪ huge part of the fun of making your own hot dog mummy is watching the process of mummification unfold before your eyes. The mummification process takes about 3 changes of the natron mix, so you can mix a big batch, in the beginning, to use for the next month or you can mix single batches each week. We can mimic the natron used to make ancient mummies in our own mummification process by mixing 4 parts salt with 1 part baking soda.

In fact, Natron gets its name from the Natron valley in northern Egypt and is a natural mix of sodium bicarbonate and sea salt. Natron is a mineral salt from dry seabeds. How to make a mummy (out of a hot dog or chicken) 1. Place your hot dog in a snack bag ziplock and cover in Natron mix.You can keep the learning going through a variety of osmosis experiments we have listed below as well as by engineering a sarcophagus for your new family member. So plan ahead and know that each week you’ll need about 20 minutes to weight, and change the natron mix of your mummy. This Halloween activity is a long-term activity, and it can’t be sped up to meet a deadline. If you want to make a bigger mummy, plan on about 10lbs of salt for a cornish hen mummy. Unlike the Egyptians, who used about 500lbs of a Natron mix per mummy, we will only use about 2-3 lbs of salt for each hot dog mummy we make. Yep, it goes that fast! In fact, in ancient Egypt, the mummification process took about 40 days, for a full grown adult! Since we’re dealing with much smaller items they mummify much faster. You need about four weeks to mummify a hot dog or a chicken.
