So the general idea behind inkjets is to shoot tiny, fluid blobs of ink onto the paper. The ink is held in a tiny, open nozzle where the surface tension is enough to prevent it from leaking out. To eject ink from this nozzle, there are 2 popular methods: 1) (bubblejet) inside the nozzle, there's a resistor that heats up, vaporizing ink and forming a ink-vapor bubble. As the bubble grows, it pushes just the right amt of ink out the nozzle; as it pops, the low pressure created draws more ink in; 2) (piezoelectric) there's this special material in the nozzle that expands & contracts when you hit it w/electricity... the expansion/contraction pushes ink out & draws more ink in.
But more to the point: this thread is now about cake. I love rich, chocolate lava cake with some vanilla ice cream. How about you guys?
