Answer:Using a Winnowing Basket: A traditional method where a flat, woven basket (bilao) is used to toss grains into the air, allowing the wind to blow away the lighter chaff while the heavier grains fall back into the basket.Shaking Grains in a Tray: Place grains in a shallow tray and shake it gently; the lighter chaff will be blown away by a fan or natural breeze while the heavier grains remain in the tray.Using a Hair Dryer: A hair dryer can be used to create a stream of air to blow away the chaff from grains when they are tossed lightly in a bowl.Manual Tossing: Simply toss the grains into the air in an open space on a windy day, allowing the wind to separate the chaff from the grains.Using a Sieve: Pouring grains through a sieve can help separate lighter impurities, although this method is more akin to sifting than traditional winnowing.
