Don't soak them, just put them between moist, (not wet!), paper towel.
No need to put them in a bag, just a cover of some sort, maybe between two dinner plates like a UFO works well, as in one plate normal way up and the cover plate upside down on top of the normal plate, and keep them in a dark, warmish spot and most importantly, do not let the paper towel dry out, which is highly unlikely if kept covered.
Remember, moist, not wet and you should be ok.
Otherwise, using grow wool cubes is super easy - if you are keen on this method, I have posted a tutorial for rock wool germination in my diary "cannabis conundrums", - in the "germination week" obviously!
Hope this helps, Organoman.
