A popular TikToker is blowing minds with a clever hack for opening a can of soda -- by using another can of soda. Jordan Howlett showed his 10 million followers how to pop open a soda can without having to use your fingers and risking your nicely manicured fingernails. He explains that the bottom of a soda can is purposely designed with a circular ridge so that if you place it on top of another soda can, you can use it to pull back the tab and open that can. He says that's why the cans stack so perfectly. Try it yourself.
