Not well and they are more trouble than they are worth. For teeny tiny pinholes that create slow leaks, they do work. Anything bigger just gets sticky crap all over the tire, tube, wheel, and whoever the poor slob is that has to replace the tube. Valve stems get clogged with the sealant too. Like fietsbob mentioned, wait until one explodes if you want to see a real mess.
The tire sealant goop works much better on tubeless tires like those used on ATV's and lawnmowers.
