As a rainy Saturday morning breezes through my face with me sitting at my laptop out at the balcony , I bumped into this really eco-friendly video. Imagine Jollibee and all other fast food chains saving all their used deep frying oil to sell it to us. That's because the guys at Mythbusters honestly say that this is a biodiesel, and to be honest i really do not know why we havn't practiced it in a grand scale! Just watch the video.
