Neat! However, I'd say this is a right-way-around bubble. Bubbles are (usually) a gas in a liquid. Like this. The only difference here is the liquid is 2d. ... and the other only difference is that instead of the gas pushing, the liquid is pulling. So this is a right-way-round 2d stable cavitation bubble.
We've found your book and bought it for our 5 years old kid. He loved it! Even teachers and other mums did. And now I got hooked in your UA-cam channel without even realizing that you were the author of the book. How cool is that?! Thanks for all your work, now I've become a fan!!
Huh… It's very unlikely that I would have thought of this. But with your explanation, it makes total sense. The film of soap holds the string suspended from all directions like a suspension bridge, and the string's shape becomes a circle, rather than some other shape, because it is being pulled on equally from all directions. If the string was another shape, you could tell where is it was receiving a stronger pull from, by looking for outward pointing bumps or spikes, and tracing from the center of the hole to the furthest point of the bump or spike in the string. It's like if a suspension bridge used a net instead of a cable, to hold itself up.
Nice video. I knew most of these things already but your perspectives are always fresh and your presentation always new and highlights aspects of a concept beautifully. Thank you, Steve. This channel deserves 1 mil subs.
My physics teacher used to do this soap bubble trick to demonstrate surface tension. I haven't seen it since that day ( many years ago ). He also used to place drops of dye onto the surface of the bubble, but I can't remember what he was demonstrating with doing that. Knowing him it might have been just for fun. He was called Mr Senior and was the best teacher I ever had. 😁
This is clearly the first step toward Portable Hole technology! We still need to allow storage, increase the hole diameter to 10ft, make the storage persistent, increase the range of surfaces that it can be applied to, and make it seamlessly close the gap behind it, but I think you've got the core of the work done here.
Steve you’re an amazing content creator and I’m glad you showed off the books, im definitely going to purchase them for the younger siblings in the family
That looks so cool! I used to make a "psi-bubble" in the shower as a kid. I would put soap in my hands, make a circled at the thumb & index finger, blow through it with my other hand to catch it, close the hole and viola! I used to take hour long showers because of stuff like this.
I usually learn a lot from these videos. This time I was quite proud of the fact that I already knew all of this stuff. However, being that it’s all stuff you put in a children’s book, I’m not so sure that I should be that proud.
So cool!! I always look forward to your videos, Steve! Such a great mix of dry humour and genuine science, wrapped up in such a way to make it approachable for anyone! Brilliant work as always!
I'm so glad your subscriber count seems to be rising well in 2019. You make amazing videos and really deserve to be getting more subs and views. Keep it up!
That's a very fascinating concept! I always loved science books for children and I can't imagine how much impact these books will have on the curiosity of children who get to enjoy them.
"I'm not going to bang on about it that much" says the guy who, unbeknownst to me despite my avid viewership, has now published three amazing looking books, perfect for our kids, that I totally need. Bang on man!
i can see a secondary property where the bubble acts as a level, or in this case a disk level. i can see that your set up is slightly askew, pointing down towards the upper left of the frame and up at the bottom right (1:19) or at least the rough wire frame shape and the stand holding it is simulating this in that way. all in all a great experiment and in my mind possibly an inverted disk level, but anti-bubble works as well.
Great video! Definitely liked all of it, but the real reason I left a like is for the honesty about using a click bait title for likes. 😆 It was delivered perfectly. 😊
I cant believe its a 2019 video with a clickbait, but then it shows actual content from the first second of the video. I hope this comment gets discovered by future generations, so they know who were the heroes on youtube in 2019
You can also say that the tension pulls it in all directions evenly causing a circle. The tension pulls it in all directions trying to minimize the area since the bigger the area the greater the tension.
Hey Steve, that's very interesting did not know you could do that. bubbles are fascinating. Notice the colors of the bubble film I have found this interesting and beautiful for a long time. It would be awesome if you did a video on this. What I have observed is if you just have a flat vertical bubble film you can observe the Colors filtering from bottom to top. First is multiple bands of teal and Pink then bands in this order: green, pink, yellow, green, blue, purple, pink, orange, yellow, light blue, dark blue, dark purple, orange-ish brown, white, silver, clear then it pops; seems to always happen in this order. The best way to see vibrant colors is hold the film so it is reflecting a bright light. you can see it pretty good at 1:19 in this video. I think the reason this happens is that gravity is pulling the small amount of water trapped between the two layers of surface tension and getting slightly thicker towards the bottom. I think the different thicknesses reflect/refract different wave lengths of light, probably even UV light being reflected from the clear part that we can't see.
Steve, after reading through the comments I have some suggestions for a follow-up video: Tie the string into more complex shapes, including a trefoil, a square mesh, and a hexagonal mesh, each with at least 6 cells, and experiment with the resulting shapes. I expect you will get honeycomb shapes of various sorts. Reshape your film from planar to a hyperbolic paraboloid by keeping two parallel sides of your square straight and bending the other two sides “upwards” into a parabola. The resulting film will have negative curvature and your hole should float to the middle (which from a potential energy point of view is the “top”) instead of drifting to the low side as it does now. Try polarizing lenses to see if you can visualize the different thicknesses of the film. And, as multiple people have suggested, some high speed footage might be very instructional.
Here is another fun and easy experipent that you can try: turn a water tap on a little bit so that you get a small stream of laminar flow. Let the stream fall into a cup of water. It is now possible that a bubble of air will stay in the water under the stream. It is exactly the same effect as when a pingpong ball floats above an upwards stream of air from a hairdryer. Only now the stream is downwards and the bubble is pushed upwards by the buoyant force.
I had no idea you did books, you should sell yourself more, after all this is the perfect platform for it, even if the demographic isn't exactly the same age group, we all have families, plus books like these are perfect for getting a kid interested in these kinds of subjects.
Is the hole going down because the thread makes the hole heavy or going up because the missing soap makes the hole light? Is there a transition point where those two cancel out?
It might also be trying to move towards the knot, because it's a disturbance in the otherwise circular shape. In effect, the string is pulled outwards all over but the knot has a bigger circumference per hole-centered angle that cannot be resolved. More experimentation recommended! :)
Good question.. My guess is that the hole would move away from the centre because the film would be thicker towards the edges, meaning more elasticity? But I'm no bubble scientist, don't quote me. Edit: Then again, if it was curved so that the centre was the lowest point then that would also be the thickest, meaning the hole would rest there? Man, you've blown my mind.
0:14 - 0:25 You are unbelievable and awesome 😂 I thought, WTF who would call it negative bubble or anti-bubble, that's so wrong ... and then I heard your explanation 🤣👍
Going by your excellent videos, I'll have to also get organised and by your books for my boy and his cousins :) Really love the way you explain the world the lies beyond our senses 🏆
My daughter and I tried this out, but unfortunately made the mistake of using a hair elastic instead of thread. In hindsight I should have seen why that wouldn’t have worked so well - it resists the pull of the soap so while it floats in the soap bubble and you can pop the bubble inside the elastic, the effect isn’t as noticeable because it doesn’t get pulled into a circle. Still, after the failed experiment we had lots of fun playing with bubbles. Thank you for the neat experiment suggestion! I’ll definitely consider getting your books in a few years when she’s closer to the recommended range. We’re always on the look out for books that understand education is best when it’s kept fun.
Those books have amazing cover art! If I had kids, I would buy them in a heartbeat. Maybe I’ll steal some children so I have a reason to buy your books. Also, great video, as alway! Keep up the incredible work!
