Place the first half into the seed extractor and cover with lid.
Take a large metal spoon or flat fork and tap multiple times from the top down, hitting different spots on the lid to make the seeds fall into the container.
Repeat the operation for the second half of the fruit. Before discarding each half, check the inside for areas where seeds remain, then finish tapping that area without the lid to remove these extra seeds.
Place the seeds with their skins that fell with them into a mid-size bowl. Slowly pour cold water on top and gently mix with your fingers to make the skins float to the top of the cold water.
Remove skins and continue stirring with your hands until you were able to remove most of the skins. Some small amounts will remain, but the vast majority will be gone.
Strain the remaining seeds and serve into a bowl to eat on its own, or mix with your ingredients of choice.
