Take two pieces of hacksaw (can be used), the wire must be selected slightly thicker (soft, easy to operate,) should be able to withstand at least 1000 watts (2.5 or more), a piece of fire wire, and another piece of zero line The two pieces are separated by two bamboo chopsticks, and then the three are tied tightly with a cotton thread and laid flat on the bottom of a container made of non-conductive material filled with water, and then the plug is inserted into the power outlet, but the sound is a bit Intimidating, the speed of boiling water is still very fast, but should pay attention to electricity safety, timid must pull out the power before they can test the water temperature, as long as any parts of your body are not grounded, then you can go to try.
