In recent years, we have seen the internet craze over the Blue Dress vs Gold Dress. People looked at the same dress and some saw a blue dress while others saw a gold dress. Then there was the Laurel vs Yanny effect. Some people heard Laurel while others heard Yanny. Well, the latest one since 2018 is the Green Needle vs Brainstorm. There is an audio file that if you think of either one of those words before you hear it you will hear that word. If you think Green Needle, that is what you will hear and if you think Brainstorm, that is what you will hear. You can try it yourself here: https://tinyurl.com/aztfhvjr.
