  1. IMO This video did not seem rushed, it seemed concise.

    I'm stepping through them in chronological order, but so far the effect of time constraint appears to have a positive impact upon your narrative.

    Incidentally, since my other favorite video thus far was the surface tension one, mixing illustrations in really makes the video feel more informative as well. <3

  2. we need more girls like you in the world. Im majoring in astrophysics and no one except  myself and my peeps are ever interested in how the world around us works.

  3. Does this happens only with ping pong balls? Or it would happen even with  tennis ball, baseball or a cricket ball?

  4. you used the music from david mitchell's soapbox!

    … which i guess must have come from somewhere else too…

  5. try taking a funnel and hold it upside down. put the ping pong ball in the wider side and blow through it. the ball will not fall even when there is nothing holding it up. I can't understand it.

  6. you are awesome. Am an engineer but not a physicist but i would change my profession all together if am given an oppurtunity.

  7. I just found your channel!!!! I love it!!!! And you are so awesomely wonderful, beautiful and GROOVY! I'm gonna keep physicsing!!! 🙂

  8. The Coanda Effect is also the main force that creates lift in a wing contrary to popular aerodynamic theory. You can still find Bernoulli Effect in text books to explain lift.

  9. Hi Physics Girl,

    thanks for your video! Im a german science/knowledge YouTuber and looking for some interesting videos. My last video is about "how fly a plane". The coandă effect is essential for this. I love your chalk animations. Its nearly the same how I animate (I use chalkboard background + chalk animations). I also like that you are interest in physics and more. 🙂 I know you before from a recommendation of science event but now I saw a video and subscribe you. Im looking forward to see more videos. 🙂

    best wishes Finn

    Sorry for my bad english. 😀

  10. Love her stuff and I don't mean to be a troll, but the thumbnail for this video looks like she's lighting a crackpipe… 😳

  11. You are amazing mam! Perhaps physics is more interesting when we apply it by ourselves! Genuinely I would not have understood this if I had not performed it myself after watching your video! Your all videos are fantastic! The way you explain is superb! Keep inspiring like this!

  12. Yes it was rushed, but you explained it so well, I was quite surprised when you said it was only 60 seconds. Well done. Thank you

  13. This reminds me of the episodes MinutePhisics did … the couple of stuff explained in 9.99999… seconds…

  14. Does this also works on golf ball? Since it as pores on the surface it will create different air movement than ping pong ball. The same mechanics might work but the effect on the ball might differ?

  15. I can't be the only one who thought the thumbnail image of this video looked like she was smoking crack…(?)
    "And she seemed like such a NICE girl…."

  16. hi what is different between coanda effect and bernoulli's principle(both are same or different), plz explain it.

  17. Like virtually all physicists & aerodynamicists she only gets it partially right and discusses suction without including….[guess what it is].

  18. I did not know that if air is blowing on an object that if there is an area of low pressure that the object will move toward that area of low pressure.

  19. Your thumbnail for this video looks almost as if you’re doing some sort of drugs, at least to someone like me who’s not really hip to the whole drug culture but has seen a lot of movies.

  20. I saw this video about 2-3 years ago when I was in 8th standard. Now in 2019 I'm in 11th standard and again came here after reading this concept in my textbook. 😀. Thanks a lot to you, you are a real physics girl as you made a 8th standard child understand a concept of class 11th with so ease.

    Love from India💖

  21. If you suspend a ball and stream of air put your hand above the ball and lower it towards the ball can you guess what happens?
    The ball begins to descend before your hand touches it.

  22. Your explanation is equivalent to the Bernoulli principle, right? I would say the difference is more pedagogic, you say the reason for air following a curved surface is due to low pressure. On the other hand, the Bernoulli explanation is that there is low pressure due to high velocity air flow along the curved surface. I remember that once our prof told us that this works also with a stream of water! I remember that he used it as an example for the Magnus effect, i.e. that the spin of the ball plays a crucial role. Would you agree?
