Not very magical unfortunately, but gravity is involved. I don't own an auto siphon, so I have used a racking cane for 1.5 years now. Fill it 1/2 to 2/3 full of no-rinse sanitizer (I use StarSan solution). I find a turkey baster works best to fill it from my 1 gallon jug-o-sanitizer.
Place the rigid cane in the vessel to be transferred from. Raise the floppy end until the sanitizer comes within an inch or two of the top of the rigid cane and plug the dry end with your thumb. Keeping it plugged, drop it down to the level of your empty vessel.
At this point I unplug the end. Gravity forces the sanitizer to drop, which creates the vacuum to start the transfer. I usually catch the sanitizer in a bowl until the beer starts to flow. Cheers!
