He Made This In Less Than 3 Minutes And It Cured His Muscle Pains - Plus It Cost Nothing

To do this, take a sock - preferably a clean sock you will no longer use. Fill with dry rice and tie it to close it. Put the rice-filled sock in the microwave for about one and a half minutes, until it is hot. And just like that, your hot pack is ready! It is also reusable and you can reheat it as many times as you want.
