Can you recognize such a cute handsome guy? Blindfolded to talk about products, cute and cute, there are still tens of thousands of people waiting here in the live broadcast room at night. Peng Peng's lectures are getting better and better, and they can always be linked to the knowledge of mathematics, physics and chemistry. For example, this heat-generating eye mask is an exothermic chemical reaction between iron and oxygen that uses the knowledge of chemistry
4Fe+3O2=2Fe2O3
This is equivalent to reviewing the knowledge that you have almost forgotten.
In addition, I also listened to Peng Peng talk about the problem of snails climbing the well, and left the problem of bottle caps, it is said that it is difficult to be very interesting, and I will explain the method next time I broadcast it. Waiting here, almost forgetting the time. #与辉同行#
