Homework Help: Physics behind this bottle holder?

  1. Feb 13, 2010 #1
    1. The problem statement, all variables and given/known data

    What is the physics behind a balanced wine bottle holder. Something like this....http://www.thetipsygrape.com/product-racks-bottle-holders-straight-wood-bottle-balance.html

    2. Relevant equations

    No equations.

    3. The attempt at a solution

    I didn't know where to ask this question but I'm guessing this has to do something with the center of gravity and the angle that the wood was cut.

    I would guess that the wood is angled so that any ~ 750mL bottle stuck in there would cause the centre of mass to fall right thru the base of the wood, thus allowing the contraption to balance.
