The speaker, Michael from Vsauce, is discussing various topics during a segment of his show. He mentions that the eye is a mirror, and when you look into it, you see a small version of yourself. This is where we get the word "pupil" from, referring to both a young student and the dark hole in the middle of your eye, where you see the tiny version of yourself.
He is working with Adam Savage on their tour "Brain Candy Live" and is giving him a tour of his desk, filled with various items he finds interesting. He mentions a Stirling engine, a precision-made object powered by the heat of your hand, and a chunk of India, a soft metal that gets softer when warm but is also non-toxic. He also talks about how air pressure is affected by the temperature of the air, and how the pressure inside a container can push against the walls when the air inside cools down and expands.
He discusses the concept of suction, explaining that nothing really sucks; instead, the atmosphere pushes the air into the object. He also talks about the importance of visualizing things in your mind for building and solving problems, and how he uses puzzles to exercise his brain.
He goes on to talk about his desk, filled with various items including puzzles, a density cube set, and a beaker with milliliter measurements. He also talks about his love for globes, mentioning a bespoke globe made by Ballard b globes that he received as a wedding gift.
Finally, he discusses the phenomenon of all humans blinking their eyes at the same time. He mentions that the chances of this happening are very low, even given the number of days in the universe's life so far. He concludes by thanking his audience for watching.
