Ever notice how larger objects (like Brazil nuts) end up at the top of your cereal packet!? Physics can explain this. More at http://www.sixtysymbols.com/

Is funny, Brazil nut in Brazil is called "castanha do Pará" or Pará(state in Brazil where she comes) nut, probably in Pará is called only nut.

NO... in Brasil is called: "O efeito noz"

I love that everyone loves pointing out the m/s mistake. Trust me, he knows what the units for acceleration are. It doesn't make you look any smarter by correcting a misspoken word, it just makes you look like a asshole.

In theory yes, but I suggest not shaking it if the item is valuable/fragile... hmm next time I get Cracker Jacks Ima try this trick

[sayan roy]

aceleration's SI unit is m/s^2 not m/s ,,, anyways ,it's a mind-blowing vid ,,,but,can any1 explain the last 1,,,the significance of water.

Would have been great having a teacher like this when I was in school! So, next time I receive a package in the mail, filled with a few small items I ordered, plus massive amounts of those crazy-making Styrofoam "peanuts" - all I need to do is shake the box and all the items I purchased will come to the top? I will experiment first chance I get. Oh yeah, and when we were kids and prizes came in boxes of cereal and Cracker Jacks, we wouldn't have had to dig through or dump the contents?! ;)

meters pr second is not the unit for acceleration! It's for velocity.

My Snapple cap told me about this.

Why do the led pellets form stripes? and why do the aluminum pieces come together? Does their density make them react to the shaking similarly?
