Parshas Va'era

Well, for all we know, they might have used hollow reeds…

A children’s illustration is not meant to be a realistic depiction of an event, it’s to explain a concept. In this case, that a Jew and a Mitzri could drink from the same cup, one getting water and the other blood.

I once saw a picture (in a book published by a certain large Chassidus) for parshas korach, with Moshe and Aharon wearing streimels and korach had a bend down hat. Now why would they have had streimels if it was during the week, and if it was Shabbos, nobody could’ve taken the photo anyway. It couldn’t have been motzei Shabbos because it would’ve been dark and flashes weren’t invented yet.

from Wikipedia:

The first known straws were made by the Sumerians, and were used for drinking beer,[1] probably to avoid the solid byproducts of fermentation that sink to the bottom.[citation needed] The oldest drinking straw in existence, found in a Sumerian tomb dated 3,000 B.C.E., was a gold tube inlaid with the precious blue stone lapis lazuli.[1] Argentines and their neighbors used a similar metallic device called a bombilla, that acts as both a straw and sieve for drinking mate tea for hundreds of years.[1]
