In the eyes of most people, engineering laboratories are places full of poisonous gas and plague. Students wearing thick "bottle bottom" glasses wear white coats and plastic gloves and perform hard labor under the pressure of strict and BT bosses.
In fact, engineering experiments can be very interesting. Although there are a lot of embarrassments and experiments often go unsatisfactory, it is full of joy. Of course, maybe it's just a joke...
My laboratory life is embarrassing and happy.
