Do you remember the infamous Tumblr dress that was either blue or gold, or that mind-bending audio clip that either said “laurel” or “yanny?”

How could we forget, right?

Well, there is a new illusion blowing people’s minds. In this viral TikTok video a man’s voice either says “brainstorm” or “green needle.”

It changes depending on which phrase you decide to read on the screen!

Try it for yourself:
