At the top of all the little tubes that would normally have an air bubble,
there's an airline tap (just like the ones they use in the stores to tap
1/8" tubing to the big PVC manifold supplying the main air to their
tanks).  The valve is unscrewed, the air sucked out, and the valve
reclosed, just like starting a siphon.
