I Sucking up spaghetti

    I am a fairly long-term homework helper, but this is my first post to the Forum.

    I have often wondered: where do the forces arise that allow me to (rather impolitely) suck up individual strands of spaghetti? I deliberately create an imbalance in air pressure between the inside and the outside of my mouth, but the air pressure acting on the spaghetti produces forces that act perpendicular to the spaghetti's axis (not towards my mouth), with only the force on the very small hanging end acting along the axis, to push the strand up. So, how does the spagehetti get sucked up?
