1. A spike for dispensing a liquid from a bag, the spike comprising:
a shaft comprising a proximal and distal end and an elongated body therebetween and having an outer surface; a puncturing tip at said distal end; a first channel internal to said shaft, said first channel having a first fluid inlet on said puncturing tip through which fluid can flow through said first channel when a bag containing a fluid is punctured by said puncturing tip; a second channel internal to said spike, said second channel being noncontiguous with said first channel and having a second fluid inlet on said outer surface below said first fluid inlet through which said fluid in said bag can flow through said second channel when said bag is punctured by said puncturing tip; a first aperture at said proximal end allowing said fluid to flow through said first channel; a second aperture at said proximal end further from said distal end than said first aperture, said second aperture allowing said fluid to flow through said second channel.
