Very cool! Tie-in between SciShow and Alexis Dahl:

It's so fascinating that the purity of the copper was the downfall behind the tools (makes sense considering that other cultures went with bronze and not copper tools - bronze being an alloy)...makes sense given that copper is known for ductility rather than particularly notable strength.
Alexis is also on Nebula:
Alexid Dahl with another very intersting, awesomely presented video about a historical site in Michigan.
NB: Sometimes "historical" is the last few centuries, sometimes it's a more geological historical, back up to billions of years !
She does a great job with all her videos - but this one on the Soo Locks should be a must watch!
Want to shut down the U.S. Steel Industry? Stop taking care of the Soo Locks.
A few years back, when maintenance issues created an outage - members of the U.S. Congress had to be educated on just how critical the Soo Locks are.
