Former NASA engineer. Current AL-gosr and friend of science.
Answers to some common questions:
1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC.
2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). I founded a company called Digital Dudz on my nights and weekends while working at NASA (also made some videos about that) and sold it to the guys who make Morphsuits in the UK. As part of the sale I quit my job at NASA and worked for them coming up with all their new costume ideas for 2 years. Recently, I was presented with an opportunity to return to my Engineering roots to come do some ideation type of work for a tech company near San Francisco.
3) Link to free and therefore substandard build plans for my custom workbench can be found below.

    The kids and I love your videos. We immediately went and did the paper clip and pepper experiments after watching your livestream. BUT now we have more questions! When we put our paperclips to float in the bowl, WHY do they seem to stick to each other? I know they're steel, but they're not magnetized, and they don't seem to act with any polarity the way magnets would. But it's nearly impossible to get them to float separately-- they always want to clump together like a giant paperclip raft in the middle of the bowl.

    Sooooo... I don't know about your conclusion. ◸ ◹ A test: *you'll need a highspeed camera and an airtight box filled with the different mediums* Tap a tuning fork within the medium. ◺ ◿ Look at how quickly the tuning fork vibrates in each medium. Get another trillion views. Sound travels faster in helium than in "air" (the mixture of [mostly] nitrogen and oxygen we normally breathe). The velocity (v) of a sound wave is equal to its wavelength (λ) multiplied by its frequency (f), v = fλ. The speed of sound in normal air is ~345 meters per second. In helium that speed is ~1007 meters per second, and ~134 meters per second for sulfur hexafluoride. My hypothesis: Your vocal cords aren't moving faster or slower -- the frequency of your vocal cords' motion stays the same -- the energy transmitted from the vibrating vocal cords is being applied to the different mediums. This changes the speed of the sound wave. By changing the medium (the atmosphere) a sound wave travels faster or slower. The frequency of the vocal cords' motion remains unchanged, but the speed the waves are carried away through the various mediums do. I love your work.
