supplies for co2

get the parts and put it together. buy the co2 tank.... find a cheap regulator buy a needle valve and hook it on..... Solenoid too if you want..... though a lot of people just break down and buy one put together. they have some one ebay as cheap as 60-70 i think with better ones 90-100. yes its more money then diy co2 to start with but its worth it. one of the few things you can buy set and almost forget about.
 
by cups of sugar do you mean like drinking cups? that just seems a bit much

They mean a measuring cup. Where 1 cup ~= 1/4 liter. It's actually closer to 0.2366 liters, but 1/4 a liter is close enough. It doesn't have to be exact.
