It was a cool day up there in the frosty temperatures of Gotong Jaya but frosting very quickly down the back of our necks was the realisation that there was absolutely no wind compelling the leaf to sway. What was the cause of the plant’s bizarre behaviour? Naturally, we all jumped to the first conclusion: Hantu.
As The Mystery DeepensIntrigued, a search on the Internet (what will we ever do without dear Google?), revealed that apparently, lots of other plants have been found to behave like that as well! “Our” leaf in Gotong Jaya wasn’t the only one to dance alone. There are countless recordings from all over the world posted on You Tube of plant leaves that sway and wave and swing from side to side all on their own.
Most of the people who have seen this, attribute the phenomenon to the paranormal (I mean like what else, right?). In fact, one video recorded in 2013 by a North Carolina couple Jason Freeman and wife (reported in the Daily Mail and countless other online portals) raised so many viewers’ goosebumps, it went viral, garnering more than 594,211 hits to date!
Freeman’s Video is appended Below (His Swaying Leaf is even MORE phenomenal!)
In the video, Freeman sounds spooked and amused at the same time, laughing out loud and saying “This is really creepy!” all the time.
Here is another Video that is not so Popular but shows the same Phenomenon
Paranormal InvestigationOn closer look, however, one thing stood out: There seemed to be a similarity between all of the purportedly haunted, self-swaying leaves; and the clue was in their shape. Most of them were of the long and slender variety growing top-heavy from a reedy stem.
Yet One More Video of Moving Leaf
Down to Earth with a ThudBut it seems that truth is plainer than fiction. Much as we’d like to believe that the supernatural is the invisible hand swaying the leaf, there really is no ghost in the plant after all because science has the proof.
The American Journal of Botany’s study titled “Oscillation frequencies of tapered plant stems” puts paid to the mystery because it says the oscillation of the leaf is in fact, caused by the wind.
Weak wind, imperceptible to humans, is strong enough to magnify the plant’s resonant frequency making it move on its own.
The researchers Hanns-Christof Spatz and Olga Speck wrote: “Free oscillations of upright plant stems, or in technical terms, slender tapered rods with one end free, can be described by considering the equilibrium between bending moments in the form of a differential equation with appropriate boundary conditions…..”
They further said: “Knowledge of the resonance frequency particularly in the fundamental mode of oscillation is necessary to assess a plant’s stability against dynamic wind loads (Kerzenmacher and Gardiner, 1998).”
It was the wind after all.
And there ends our Mystery of the Swaying Leaf. I always suspected there would be physics spoiling the fun. But other than the leaf that spooked us somewhat (which is why we still remember the incident to this very day), we had a wonderful time, walking among friends in the cool, green surroundings of the secluded hillpath and marveling at the wonder of the wilderness captured in the photographs above and below. That hiking path is no longer accessible to the public, sad to say. They locked the gate and threw away the key a long time ago.
But not to leave you walking away from this post deprived of a real ghost story, here is the link to 6 from National Geographics’s 2014 series I Wouldn’t Go In There as consolation. According to Nat Geo, the stories of haunted Asia (including Malaysia’s haunted War Museum in Penang) are as real and as true as they come, and will surely give you a mighty good scare.
Happy ghost hunting!
