易拉罐喝前为什么要擦一圈

家人们一定要记得擦易拉罐口！易拉罐口到底有多脏？ today on how jeremy is it we're going to be testing gas station， soda cans and for this test i'll grab a cola and an energy drink now to grab the samples so i want to make sure that i'm testing apart that you care about the most where you put your mouth to see what may be harboring in those refrigerators and just for fun i'm going to test a soda straight from the box then put them in the incubator and see what we find out this is the soda straight from the box okay， not too bad but i was expecting there to not be any growth at all now for the energy drink okay， that's definitely not what i wanted to see for the cola can so my suspicion is that the filtration inside these refrigerators aren't changed as often as they should be。 看完这个视频，我真的狠狠记住了！饿之前一定要擦一擦！
