This post might seem a little random, but I stumbled across this video and was floored by how complicated the manufacturing process for this simple soccer ball (sorry, football for the rest of the world) is. The amount of technology, machinery, computers, and undoubtedly, energy going on here is HUGE.
Remember that this is a mere football. A ball. Filled with air.
Then imagine how complex the manufacturing process is for other seemingly everyday objects.
I watched this and had to think about my house, made mostly out of sand and clay, which was built almost entirely by hand. The level of technology in my whole house seems to pale in comparison! (Ok, so there are some materials in the house [windows, the EPDM] that are probably quite complex to manufacture, but still…)
