Us Egyptians used hieroglyphics to write, instead of the regular alphabet.
I know it may seem strange, but we used things like human brains and whole cooked mice to cure many illnesses.
Makeup was very common and it was used by all Egyptians. Dark eye makeup called kohl was made of soot and other minerals.
Our bread had lots of grit and sand in it, so it was hard to clean our teeth. So, we invented the toothbrush and toothpaste. Toothpaste included ashes, eggshells, ox hooves, and many other ingredients.
Building ships was a big part of our technology. We originally built small boats from papyrus reeds, but later built large ships from cedar wood imported from Lebanon.
We had our own numbers that we used for math. We needed to know math and geometry for building pyramids, as well as other buildings.
