While slightly labor intensive, extracting the seeds yourself is very rewarding and gives you an appreciation for what it takes to enjoy pomegranate's splendor (and is a fun sernsory activity to do with kiddos!) Fill a large mixing bowl with cool water. Rinse the outside of your pomegranate and with a large kitchen knife, slice into quarters, halving through the stamen end (the top that pokes out) and then cutting again. One quarter at a time, submerge the pomegranate into your water-filled bowl. Gently, but firmly, rub your thumbs along the arils to release from the white pith. A few may break, but don't worry! If needed, break the pith apart into smaller pieces. Keep going until all of the arils are released! They will sink to the bottom of the bowl while the pith floats. As you go, keep removing the pith to make more room for your hands. Once all quarters are done, skim off the top of the water to remove any floating pith pieces and strain the arils. All done!
