On October 12th, I went to Longtian Elementary School to conduct a diverse ability workshop in the field of natural sciences in primary and secondary schools. Especially when making clouds and qi roots, some teachers seemed to start pressing alcohol in a plastic jar and started pressing. After pressing the bottom of the bottle and opening the lid, the bottle was very interesting. And the experiments of Zhenyin's teachers are actually Jiao Er Steal, because it is really difficult to imagine that you can put the battery that has no power to return the circuit to make the LED light bulb light up again. There is no electricity, but because the battery's voltage is not enough, there is no way to let those electrical appliances operate, so in fact, Jiao Er Shen stealing is to add some 1.3 volt batteries to the circuit of the inverted ear stolen. We do this experiment and feel amazing, mysterious, fun and fun.
