Subject: How do I increase the voltage in my home made battery

I have built, with the help of my uncle, a home made battery.  I have used 
six 2x3 inch pieces of aluminum and six 2x3 pieces of titanium.  I am 
using tooth picks as an insulator between the plates.  I am using 8oz. 
vinegar to start the corrosion process to produce electricity. I can only 
get about 1 volt from my battery.  The voltage drops off rather quickly 
when I hook up my 3 volt bulb.  Any suggestions on how to increase my 
current flow?
