Does the toy say 'brainstorm' or 'green needle' ? Image Credit: YouTube / Nerd Out With Me
Hot on the heels of 'laurel or yanny' comes another audio clip that seems to say two completely different things.
The new brain teaser, which is actually a short clip taken from a four-year-old review video, features a 'Ben 10' toy with a battery-powered loudspeaker that states the name of one of the characters.
The audio should be saying 'brainstorm', however many people are hearing it as 'green needle', despite the fact that the two phrases are very different in terms of how they are pronounced.
Even more peculiar is that, by listening to the clip carefully, it is possible to alternately hear both phrases - almost as though your brain's perception of the audio is flipping from one to the other.
The clip can be viewed below - which of the two phrases do you hear ?
