I have an 8 year old son who I has been exposed to the Ancient Egyptian history all of his life through my interests. He has about as many (childrens) books on the subject as I do. Even as young as 4, he could tell you step by step the whole mummification process, the names of many Egyptian deities, Pharaohs (even their throne names!). In 2nd grade, as part of a school project , he even wrote his name in hieroglyphs inside a cartouche, however, he also collects Yugi-Oh cards. He knows the difference between the true Egyptian deities and their aspects, and the phony aspects of the Yugi-Oh. When he plays the game or trades with his friend's, he passes on his knowledge of Ancient Egypt to them.
For all the faults we find of the Yugi-Oh cards, at least they show REAL heiroglyphs (I belive they are taken from the Papyrus of Ani) on some of the cards and packaging. That is soooo one of my pet peeves...when someone plasters fake Egyptian hieroglyphs all over something and tries to pass them off as real, like in movies and stuff.
For example, this $925 6ft "King Tut" sarcophagus book case. Look at the glyphs running down the center. They make absolutely no sense, I especially love the 3 martini glasses enclosed in a cartouche. I was disgusted the first time I saw this in bookcase the Discovery stall in the mall.
