Newest Head Cracker: Do You Hear 'Brainstorm' Or 'Green Needle'?

The Yanny vs. Laurel headsplitter  is so yesterday. There’s a new mind-blower in town, and this time, quite incredibly, what you hear is supposed to depend on what you’re thinking about.

The battling words are “brainstorm” and “green needle.” Sure enough, an audio clip of the words seems to vacillate between the two choices — or even “brain needle” and “green storm.”

The whole thing is supposed to function on the same principles as the Yanny and Laurel puzzler: A change in pitch and individuals’ sensitivities to certain pitches push them into one “camp” or another. 

The word “brainstorm” is stronger in lower frequencies, and “green needle” is stronger in higher ones. It’s also important that the audio quality not be particularly crisp.

In this case, apparently, the selections are so closely balanced along the pitch line that a thought might be enough to nudge a listener one way or the other — as long as the brain is “primed” to think of the options.

Reddit  user “squidjeep” originally posted the video clip of the toy that emits the sounds, calling it “black magic fuckery.”

Is there a right answer to the brain bender? HuffPost U.K.  tracked the toy in the clip to a review video  and discovered that the name of the toy is Brainstorm .
