Mozart on Fire: The Ruben’s Tube UPDATE

Look at what happens when Mozart catches fire!
What I love most about the video is their reactions. And the physics of course.

The story of the experiment was first posted in February, 2010. Preston and Jake continued their research into pressure, sound and waves. This video from May 2011 is the result of that Independent Study. I understand that it was conducted after considerable planning and research, with the approval of parents, thorough attention to safety issues (ventilation, fire etc.) and with the guidance of engineers.

Below is the original post from February, 2010.

It’s always great when a student or a teacher sends along a report, picture or a video of something cool going on in the classroom.

Or, as in this case, a cool experiment during vacation.

This is a first attempt at creating a Ruben’s standing wave flame tube showing the relationship between sound waves and air pressure. It looks quite hazardous and not to be tried at home without guidance, permission and precaution.


  1. Hi Josie,
    I really enjoyed reading about your blog. I like how you want the PDS community to think specifically and learn about different things, by using a blog. I think that is really cool. I really enjoyed reading recent posts, looking at pictures from recent\last year’s events, and last but not least, I really thought that the video with the teacher that was speaking in French was really interesting. My class and I have started a blog called Shirley’s 6th grade, and we usually post things at the end of the week, that describe what we’ve done that was fun or interesting during that week. I just want to thank you for sharing your blog with me and the whole entire PDS community. I hope you can look at our blog sometime and make a comment. Anyway, thanks for sharing!

    Hi Josie:

    The Rubens’ Tube was interesting to me because it seemed as if the flames were dancing to the music as they rose and fell. Preston and Jake did a great job explaining how the tube worked and what they did to make it. It also proves that learning can be fun. Please visit our class blog: Shirley’s 6th Grade

    Hello @Erika and @Zoe – Thank you for these comments. I will definitely be reading and commenting on your blog. I am happy you enjoyed seeing all kinds of things about our school on the blog. There are so many interesting things happening. You will have to help me keep up with them all.
    Erika – wasn’t that scene in the French classroom scary? That is one of my all-time favorite films about school and there is a lot more about what happens to the poor boy who is the main character. He is mistreated and misunderstood by everyone. And think how difficult it must have been to try and work in some fear. When I was in sixth grade we had to write with those pens too and had to dip them into little ink wells at the top of the desk.
