I started a company called CrunchLabs, where we build a toy together, and then I teach you all the juicy physics of how it works. So if you want to learn to think like an engineer and have a really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com/teaser
Thanks to these folks for providing some of the music in the video:

seated for science class
-
As someone graduated in physics, I have never seen such a clear explanation of what the coriolis effect actually is. Amazing.
-
Bro Mark Rober is the GOAT of science because of how simple he makes science so that everyone can understand. Thank you Mark Rober!

what the heck was jimmy doing there 🤣that was so random: "lemme guess, crunch labs" 🤣bro just spawned in

Regarding the backpack: when you study vibrations in engineering, you learn that there's a specific frequency in which you can vibrate a spring-mass system where it will not transfer that movement to the mass. That's why there's a "sweet spot", and all the people in the commercials were running with that sweet spot frequency, where the backpack barely moved even while they were running (i.e. the movement of the person was barely transfered to the backpack). This depends on the spring constant of the springs used, and on the mass of the system (the backpack and whatever's inside it). So if Mark were to put more weight in the backpack, he'd have to find a different running frequency in order to get the same effect. Thanks for sharing all these cool experiments and knowledge with us, Mark! You're awesome!

That backpack reminded me, if you walk with your drink, the equal frequency of your steps is building up waves in the mug, so ultimately you spill it. I do my "silly walk" with unevenly distributed steps and it truly helps make my way without spillage. With that walk I basically create waves that go against the waves I already created in the mug, mimicking how active noise cancelling works in ANC headphones.

Nicely explained and demonstrated. Answered some questions I've had. Never felt it an absolute necessity to know the answers to, but interesting to know.
-
Your explanation of Coriolis effect is really clear. I cannot explain like you even I am a physicist. Thank you.
-
If only school were as entertaining as Mark's videos...
-
"Does it work when I pour the water?" LMAO. That guy's reaction was priceless and translated perfectly into 'Ah, crap, you noticed what I was doing.'
-
Your amazing, sience is mostly hard to explain but you make it look easy. Well that is a BIG talent. Respect
-
Love the way you explain everything in Layman's Terms. Thank you for sharing all this content with all of us!!!!!!!!!!!!
-
1st time learning the difference between a Cyclone and a Hurricane. I thought one is air, the other is water based.
-
Mark would be a great science teacher really enthusiastic and explains things great
-
Mark makes science much more interesting and something that catches your attention. I also love that mark puts PVZ music with this, so relaxing and makes it much funner to learn.
-
How did I not see this 3 weeks ago. YouTube needs more of this content I hope you can keep on creating awesome videos like this one and so many others that I have thoroughly enjoyed watching as an adult well most of them
-
Mark's videos always make me feel smarter after watching them.
-
I have wanted one of those hoverglide backpacks since they were first put on their funding site. Im sooo pumped you did this!
-
Thank you for helping to curb ignorance around the globe one experiment at a time! <3
