Welcome to another installment of Science Saturday, where I highlight a YouTube channel that will open up your mind to the world of science. This week we highlight the YouTube channel National Geographic Mega-structures. From massive dams, to bridges, to the largest ships in the world, there is something that will interest and enlighten you here. They have full episodes that will expanded your knowledge of the worlds largest structures. This one is a favorite of mine in which they cover the technologically advanced super carrier USS Ronald Reagan. Kinda scary to see what it’s cable of.
