Hydrophobic Patterns Make Spinning Water Drops

I show you how how I made spinning water droplets

[ProjectPhysX]

I've noticed a similar effect with a water droplet on a hotplate. That particular hotplate has a spiral pattern ridge, so it makes the Leidenfrost-floating drop spin crazy fast.

When he said everyone has access to hydrophobic surfaces at home, he wasn't joking.

This guy starts with a calm intro and gives as a bang theory and experiment

Love you Lad ❤️

3:59 seems like we’re just “scratching the surface” when it comes to the possibilities of hydro energy.

The fact that it made a mini inverted tornado is awesome

Never expected it to react in that way

2:57 So cool when the drop is retracting back in on itself, for a brief moment, it forms the shape of a star before bouncing back up and spinning.

Wow, James would truly be everyone's dream science teacher. Easy to understand, practical and super fun!

Splash Back knowledge is very useful. I use it every day managing the waterfalls in my back yard. I use rounded rocks at the bottom of the upper fall to keep the water splashing back into the basin. or else the pond would empty in about an hour.

TLA - I want to mimic the experiment but with materials that you can find at home.
*Proceeds to use a super high speed camera to see the result*
😂 gotta love all the effort he puts into his videos ^^

[wizardOfRobots]

Very cool of you to introduce material from research papers straight to us.

[Metaldetectiontubeworldwide]

Epicly *WOOOOW*
That you recreated it with the simplest of things, spectacular cool effect ☆☆☆☆☆

I'm a 31 year old engineer who found your channel incidentally a long time ago and I have just stuck around. I've seen so many people excited about the things you do and those who seem to be the type of people that cannot be taught so they speak poorly and nitpick like children.
This channel is truly amazing and I'm always happy to see a new video pop up. Occasionally I learn something interesting or new and sometimes I'm happy to see you share something that isn't common knowledge so that other people can learn about it. This channel is truly underrated and I hope it continues for years more. You are a very humorous and amusing person and your reactions to the projects you do always make me smile or laugh.
I'm going to share this channel with my 7 year old son because he loves thing like this. I feel rude for not showing him before 🤣 knowing him he is absolutely going to binge your videos and then proceed to experiment and talk about things he has learned and tried. Stay awesome 👍

I've learnt more fun things from 1 yt channel than my whole school life

[chrisfuller]

This guy might be one of the best experimental physicists of our generation. I am amazed at how he can translate complicated physics experiments. It's clear he is putting incredible energy and creativity into his experiments! I am amazed!

This will be awesome for water catchment on roofs because you could help channel water with surface modifications and without added equipment.

[JetPen]

I would be very glad to see Action Lab collab with What if. I don’t know if it would ever happen but it will be very very interesting for sure.
❤️keep rising sir.

[ShortHax]

This would look epic in a water balloon fight

[samuelzachert]

Now I'm really curious what those applications for this would be!

[codego]

Wow, it never came to my mind that soot a resedue from fire can also be hydrophobic in nature. You have a pure knowledge. Keep it up.

[TheSlimCognito]

That was amazing. A piece of glass, a lit candle, a toothpick and water. With those things you created some amazing results. I honestly had no idea that water could spin that way. Great video.
