Sound experiment

 

Healthy nutritious food snacks are a must in my family.

I just finished a tube of Pringles®, and I made a discovery!

Have you ever noticed that if you tap an empty tube from Pringles® with your finger, the tube transforms into an exotic wooden African sounding instrument.

Anyway, the experiment is this. If you hum into the empty container of Pringles® with different frequencies, you will discover one frequency that will resonate the bottom of the container. Other frequencies will not resonate in the container. You can feel this very clearly if you hold the base of the container with your finger. This is a great mystery to me. Why do other frequencies not resonate?
  Does it have anything to do with the shape of the container? 

Has anybody got any thoughts on this subject?

 

Anyway. This is a very exciting time. We are going on a month long holiday with a lot of sun, tons of sea water, hundreds of friends, good food, and good fun. I hope that you're looking forward to weeks of sunshine as well!

1 week before my Ski Trip Adventure

  Sunday We went to Annecy. Lovely sping weather, bit cold. No snow. Seagulls on the lake. Golorious sun. Monday Still no snow. Cloudy. Temperatures about 0*C. School ended early, no music (yay!) . Spring in the air. Tuesday Heavy snow fall, started at 7:30AM. It's -2*C. It's the rush hour in Switzerland. Heavy snow and Rush hour not good combination because road clearing trucks can't do their jobs. Nyon was chaos. Roads were unusable. Interestingly when the roads are all covered with 5 inches of snow we have realized how steep the slope is from the lake to the town. The cars were stuck, slipping, skidding, doing zig zags. Everybody was a bit scared. This is the test of your winter tires, your driving skills and your nerves. We drove around town and looked from all the angles. All the roads looked dangerous and unsuitable for driving. Why were they not treated before I don't know. My french teacher who was traveling from Lausanne, left at 7:45AM and arrived at 9...

Blog re-uploaded!

Hello! It's been 3 years and a bit since I first started this blog. Since that time, I've struggled with my web host to keep it up running despite the very old blogging platform I was using. A year ago my blog completely broke.  I've finally decided to go through the long and enduring process of recovering my old database data, and migrating all my articles to something a bit more modern... Blogger! Perfect. Run by Google, this will never die on me again! The whole process was exhausting, but after many hours of work it's finally here! During these past 3 years, I've been integrating with the local educational system, and trying my best to keep my marks up! You will have undoubtedly realised that the time between blogs has been increasing. Study has started eating up a lot of my time, especially now that I am at college. I have very little free time, let alone time to think up entertaining stories. I really do hope to advance this blog on further sometime. U...

Geneva, London, Geneva

  Thursday: Today it was more like: Coppet -> Nyon (School) -> Divonne (France, diesel for car) -> Coppet -> Geneva -> London. Today was a long and interesting day. The most interesting thing was to see our plane from Geneva to London delayed, delayed and delayed until, after we took off, the Geneva airport was closed! See for yourself. Geneva, waiting until the plane finally arrives from Heathrom. Heathrow, sending planes as fast as it can, with full flight departure boards. Friday: It would have been nice to have a lay in after our late arrival yesterday. We had to take our dad to work and therefore woke up very early. The lady at breakfast asked me if I wanted boiled eggs, scrambled eggs, poached eggs or fried eggs. I said Yes. because I was half asleep.   The adults laughed and said in that order please.   I did not get this joke at the time as I was concentrating on not falling under the table.  We had hairdressers and some shopping to do ...
