Physics videos to popularize physics - any good idea?

  1. Oct 16, 2017 #1
    Hello.
    I will make some physics videos for children to bachelor thesis to popularize physics. I have a lot of ideas. However, I want to make same experiments more interesting. But I don't have any good idea right now. I think that there is a lot of creative people which could help me and give me any advice about this two experiments. I don't want to know how this experiments works. I know it. I just need some inspiration.

    1) I think you know experiment with glass full of water and paper. If I turn over the glass with paper, the watter doesn't flow out... There is different type of this experiment with bottle and pingpong ball. If you have bottle full of watter and you put the ball to bottle neck, you could do the same experiment. It also works if the bottle isn't full, you turn over it, you are still holding the ball and you let part of the water flow.

    So, I will do this experiment with bottle, both variants. However, can I use something different then pingpong ball? Some big polystyrene ball? Or something different? What about a different liquid? Is there any type of liquid when it will not works? Or have you any different creative idea what can I do with that?

    2) Maybe you know this experiment:

    I think it is great. But it is to short. What more can I do? Is there any type of liquid when it will not works? I really need some inspiration. I have done some experiment, but now, I don't have some good idea.

    Thank you very much!

    Decide what concepts you want to convey to the target audience. You could show different liquids and how different ones work. watch other videos online to see what style may work for you. Here is an example that has something similar to what I think you are talking about.

    If this is for children, and you want other simple experiment ideas, I would suggest (1) falling objects of different weights reaching the floor at the same time, and (2) paper clip floating on water due to surface tension, and (3) spray black pepper evenly on a dish full of water, put dish soap on the tip of your finger and the pepper grains instantly fly off to the far edges of the dish.
