A massive thanks to Adam Savage and the whole Tested Crew – especially Kristen Lomasney, Ryan Kiser, and Joey Fameli. Thank you so much for coming out to the desert with us, and for inviting us to your cave! Check out the video we made with them on their channel –    • Adam Savage's Penny Drop Wind Tunnel ...  

Another huge thanks to iFly Ontario for letting us shoot in your amazing windtunnel. Special thanks to Diana Rios, Treasa Telle, Michelle Brumley for having us and Anthony Jones, Torrell Henderson and Nate Roth for being great instructors. iFly run STEM education trips, where you can experience terminal velocity first hand – www.iflyworld.com/programs/stem-field-trips/

Thanks to Inland Empire Film Services and the San Bernardino County Film Office for portions of the video shot in the County of San Bernardino.

The raindrop video is from Alistair McClymont’s gorgeous artwork “Raindrop” – ​​alistairmcclymont.com/artwork/raindrop/

Video of the raindrop breaking apart is from the coolest paper i’ve read in a while – Villermaux, E., & Bossa, B. (2009). Single-drop fragmentation determines size distribution of raindrops. Nature physics, 5(9), 697-702. – ve42.co/Villermaux

  • As a Physics undergrad, this video scared me because for the first time, we saw that air resistance isn't negligible.
  • @tested
    This was SO fun. Can't wait to collaborate again!
  • When hiking in Costa Rica we found a waterfall that had a little nook behind the water. The way water was pushing the air up in the nook was exactly the right force to make the water float. So you'd lean back into that nook and watch these floating droplets swirling before you. It was totally out of this world
  • @jeffl1460
    History will show in the future that these ancient coins were left in the desert during the times of having significant change. I wonder if they will be able to make cents of it all.
  • @dizzylimme
    Imagine being an archeologist in the future and coming across hundreds of extremely rare and valuable ancient coins in the middle of a desert with no explanation
  • @robinday8200
    As a skydiver I have jumped in the rain and it hurts as you fall onto the rain. People used to joke it was because the cartoon raindrop was pointy at the top. The reality is, you're falling at 200kph and the rain is 20kph so the rain is hitting you at 180kph!
  • @26magicman26
    A penny won't hurt, but if you drop a quarter, its 25 times more deadly. The math adds up bro 🤔
  • @timmartin997
    All of my science teachers through all of my years in school were not nearly as cool as you guys in explaining this in the way that you just did and I thank you.
  • @samo4866
    You know you've reached a specific level of YouTuber when you have a mythbuster on your show. This brought back so many memories from my teens.
  • It's moving to see Adam in this. I grew up with Mythbusters and he hasn't lost any of his verve and enthusiasm.
  • @Robodude212
    Could you "stabilize" the penny's rotation by spinning it with the edge (like rolling a penny across the table, but down a skyscraper)? That would minimize the surface area and increase terminal velocity
  • I miss Adam Savage man. The guy was such an icon of my teenage years. His energy is so infectious. Really happy to see this little cameo from him.
  • @jaysonl
    Thank you for including David Scott saying "How about that?" at the end after he drops the hammer and the feather on the Moon. That's my favorite part of the whole thing.
  • @genkill81
    My heart goes out to the interns that had to pick up all those pennies lol
  • This was awesome! I'm in physics this semester, it's so cool seeing such a thorough explanation and demonstration of everything we just learned in our first unit 🙂
  • @Shockedbywater
    1:36 It is cool seeing Adam go immediately into professional mode. It's like a switch flips and he is going over exactly how the shoot will go.
  • @JadeMythriil
    Mythbusters may have ended but the spirit of mythbusters lives on in channels like this and many others that have been inspired to think, question, and experiment everything they find.
  • Thousands of years from now, people will be wondering why the hell there are so many extremely old buried pennies in such a specific and random area
  • @Lolabonezz
    seeing the rain in the wind tunnel was so beautiful i literally cried wow
  • @cliftonwk
    My first time viewing your content, I love the scientific explanations! So few people explain in detail how our world works, great job
