 recently, a piece of information about how to turn canvas shoes into "rain shoes" has been well received by some netizens on the Internet. 
 facing the rainy weather in southern China in recent days, some netizens have said that this is a good way to deal with the "wind" weather in the south. How to turn a pair of canvas shoes into waterproof shoes? Is it waterproof and reliable? 
 yesterday, reporters did experiments to verify authenticity, and interviewed relevant experts to explain the principles. 
 before the experiment, the reporter prepared canvas shoes, a candle and a hair dryer. First, turn on the hot air of the hair dryer and use the heat to make the candle softer. About two minutes later, the softened candles were evenly spread on the canvas shoes. At this time, the waxed canvas shoes were covered with a layer of white wax. The reporter scraped off the excess wax on the canvas shoes with the blade to achieve the uniform coverage effect. In order to make the candle and canvas shoes better integrated, the reporter once again opened the hot air of the hair dryer, and placed the candles on the canvas shoes. A few minutes later, the candle melted and the canvas shoes almost reverted to the color before waxing. 
 then, the reporter began to pour water into the canvas shoes which had been done "waxing". A magical scene appeared. The water was condensed into a drop of water on the canvas shoes and did not penetrate downward. It rolled on the vamp like the water droplets on the lotus leaf. The water on the vamp rolls to the part where there is no waxing, and the vamp is soaked instantly. Reporters continued to pour water without wax. When the water dripping slowly penetrated the upper part of the shoe, the spot that had been coated with candles was also gradually penetrated by water droplets. 
P, the teacher of chemistry at Fuzhou University, said that it is theoretically feasible to use wax on rainproof canvas shoes, but in practice it is not advisable. First of all, during the process of applying candles, operators can not smear wax evenly on the upper surface. There will always be slight missing parts. When it rains, the rain will permeate into the shoes along these "missing corners". Secondly, because candles are insoluble in water, when wax and shoe upper cloth are heated and fused by electric heating, they can not be cleaned. This will cause canvas shoes to permanently lose air permeability and become pure "rain shoes".
