Plow
The idea of creating a plow came from the Egyptians. For example the plows they made had room for improvement. Their plows were so light and ineffective that they are referred to as “scratch plows”. But it got worse, the plows ran off of elbow grease. But after a while they hooked their plows up to oxen which made it much more effective. Later versions incorporate straps. Without the Ancient Egypt's design of a plow we might not have one today.
