This time, we are going to test hot bags that heat up without using electricity. One of the models has a mysterious liquid and a button, but no battery. Could it be a case of infinite energy? If you watch Manual do Mundo, you know that this is not possible.
But what is a hot bag? It's a bag that usually has water inside, and people warm it up to put it on some part of the body to relieve pain or to warm up. Currently, to make it easier, there are already models that do not even need to be heated on the stove or microwave, since they have iron powder and the help of a chemical reaction.
Let's understand how this is possible? Check it out in the video!
