An interesting way of demonstrating basic physics concepts using only one relatively simple object. I would have enjoyed to see the popper drop in a more viscous fluid.

Dear Gino,

Thank you for your kind comments. I, too, would have liked to see how the Popper does in various fluids and that is an experiment we will be conducting in our science center.

Henri,

Thank you for your fun video about the Popper, an interesting object that illustrates elastic potential energy, as it can bounce higher than the height at which it was dropped -- this is probably the most interesting thing you can do with it!

You mentioned 5 lessons at the beginning, but then you only talked about 3, numbering them 1 (material science), 3 (fluid dynamics) and 4 (gravity)... or did I miss something?

Good luck in the contest!

Marc

P.S. If you have a chance to view, comment and vote on my trilogy of videos entitled "This Is Physics" --- where I try to convey the "fun of physics" by focusing on some of the greatest moments of its history --- it would be quite appreciated!

    Hi Henri!

    I like how you explain parts of physics in an interesting 2 minute video, good way to start learning, short and sweet, thank you for sharing your video and commentating and rating on mine!

      This is a good video; it's clear, concise, and interesting. I'm a little confused about the numbering of those 5 lessons though. Are potential and kinetic energy separate lessons? It's a good video regardless.

      My video is "The Cool Physics of Refrigeration." If you could watch and rate it, it would be greatly appreciated.

      Hi,

      Yours is a very nice video. As a teacher whose work would probably be improved by doing more demonstrations in lecture than I do, this was an excellent reminder that there are many simple but effective things I could be doing if I looked for them. Thanks.

      If you'd like to see and rate our video, it's at http://www.fqxi.org/community/forum/topic/2206. Thanks if you get the chance.

      Cool video. Enjoyed it and it covered so many different aspects of physics!!

      Just got you up to the magic 10 votes!!!! Looks like we need to help each other out contestants!!! I have given your video a community vote!!! Please can you do the same for mine???http://fqxi.org/community/forum/topic/2136

      It is called "convection? Heat transfer? Who cares?"....

      I hope that I can rely on you reciprocating the favour!!! Good luck!!

        Hi Marc and thank you for your comments. The one you may have missed is the potential and kinetic energy, although you mention potential energy and elasticity. The fifth one ended up on the cutting room floor as we were trying to keep the video short. There are actually several others, if one thinks about it. We left out force.

        Thanks and I will look at your submission now. My comments will be there.

        Thank you for your kind comments. The intention was to meet the requirements of the contest in the shortest and most concise manner possible. We could have expanded the video, as I am sure you are aware, but the intent was to stir minds.

        5 STARS from me!! IT IS AMAZING HOW SUCH A SIMPLE TOOL CAN TEACH SO MANY PHYSICS LESSONS!!! Thank you for this video sir, and please continue to make more!

        It's great to see how you popped out the physics behind these small things of our day to day life...

        Please go through my video also and rate it and give me your valuable suggestions... The topic of my video is - PHYSICS THE ODYSSEY...
