i notice the useful tip on the homepage for popping up maggots by soaking in coke. nice idea. was wondering if anybody who has tried this can tell me how long they typically stay buoyant for?
I like esox's suggestion of the rubber maggots, maybe mixing in some real live ones for the "wriggle effect" 
On this theme, has anyone tried threading a small piece of cork onto a hair, coating it in super glue and then dipping it in the maggots or placing the thick end of several maggots onto it one at a time?
I haven't tried it and I'm not sure if the tiny bit of cork would easily pass through the carps digestive system without causing any problems, so maybe its a question for one of the "experts"?
I suppose we could substitute the cork for a tiny pop-up boilie, but suspect the maggots would soon come off?
