I try to control myself here because so many people use the drown and paper towel root hair stripping method here. The proof it is the "Best Method" is the fact that many plants manage to live. In reality the microscopic root hairs that grow out of the tap root grow into the paper towel fibers and are ripped off every time the towel is moved. If you do not believe me get a 200x power microscope and look for yourself. I have! Then a tiny bump of the all important tap root tip during the transplant can cause permanent damage and/or death. All of this just so you can see the seed germinate? I do not get it. Just put the seed 1/2" deep in a rapid rooter or rock wool cube or similar, keep it moist and warm and it will grow.
As for soaking a seed, unless it is old or has been poorly stored that is totally unnecessary. Seeds from valuable old stock 7 years or more old may need some special treatment to coax them to life. This man germinated 40 year old seeds with this method:

I wish there was a easier way but so far my best luck has been scuffing them in a sandpaper tube, letting them set in a H2O2 bath for an hour while plunking them down every 15 minutes, and then using the GA3 at a rate of 500 PPM in distilled water with temps at the 80 degree mark from soak to sprout."
