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

  If you want something really badly, and you know your parents will say no, give it time, and they will come to you and ask you for a favour. The favour will be your deepest wish. For example, it can happen like this: I knew that my new French school will be a bother, and the early mornings and late finishing of this school will give me nightmares for life.  I noticed that from our village goes a train to Nyon. This is the supper duper top-of-the-world-and-universe train running from Geneva to Lausanne, and further to Zürich. It became my ultimate dream and ambition to obtain permission from my parents to travel to school by train.   The twice a day journey would in my mind compensate for the suffering in between.   My parents said NO  both at the same time (my parents often say the same thing at the same time, and it's usually  NO ) What to do? It's important at this point not to start begging, winging, or pressing the matter. At this point you keep your cool.   Think.

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 today. We've go
