I make these with 5mm (0D) x 3mm (ID) surgical tubing /valve rubber but silicon tube will work too ,I just prefer the rubber tubing as I think it grips better.. usually a piece of matchstick or toothpick as spigot .but anything fits will do ,5-6mm long .just pull one end off ,put over line pop end back on.the match ones are virtually weightless ,I've used bits of nails etc to make weigted ones ,like this pair one has a little brass thingy i had laying about ,in it ,and the other a cut off from 3mm copper piping .
you can even get florescent tubing ,so can make night fishing versions
I'm going to try magnets soon some tiny 3x4mm polerized bar magnets put opposing poles in the end of the tubing ,a little fely cover over the end (these are paste/flint type metal and can chip if snapped together hard enough) ,then they'll be easier to pop over the line .
I try to be funny... but sometimes I merely look it! Steve
