Cut lemon moved by itself

[mii]

Hi ,

In one of my friends place , she cut the lemon in half and left it . She saw the lemon rotated to other direction by itself .
She saw it twice on different days ,why does this movement occur ?

 

[phyzguy]

How could we possibly know? Maybe the cat moved it. Try posting a video of this happening and we can discuss it.

Welcome to PF.

How was the lemon cut? Equator or pole to pole?
How was the lemon placed, cut face down, or on its side?
Did sunlight fall on the lemon?
Was it in a refrigerator?
Who has access to the lemon?
Could someone be gaslighting your friend?

Looks like another "drive-by;" wet counter tops that aren't level do this all the time.

Maybe the cat moved it.

Or maybe some roaches.

what happens if sunlight falls on lemon ?

Lemon was cut in half, cut face is up.
It was outside .no one has access .. no gas lighting stuff . Some physics related .. could be wet surface or a plate or since
Lemons generate a bit of electricity , something triggered the rotation .

When you place a cut lemon on a marble counter top, does the citric acid react with the CaCO₃to produce a CO₂ support cushion inside the lemon? When the lemon warms, the gas expands and the lemon goes mobile.

The "sailing stones" of the Racetrack Playa, Death Valley, employ ice to do a similar thing. Nothing happens for a couple of years, then overnight everything moves.

It was outside .

The lemon is free to rotate. The shape of a lemon prevents it from standing with the axis truly vertical, so it leans slightly, like a weather vane. Then the local diurnal wind variation, like a sea breeze in the afternoon, could reorient the lemon.

It is an extremely rare sight.
It happens when a lonely lemon feels bad about something.
It was cut in half. This hurts the lemon.
The lemon then thinks "when life gives you lemons, make lemonade", so it starts to rotate to look around for other lemons.
But then it gets confused and stops since there are no other lemons around.

Just joking, of course . Lemons don't have feelings...

...as far as I know, at least. But then again, who knows?

I see that people missed the most important question. Does this work with limes as well, or only lemons?

I think we need to blow up a few balloons, then carry out a group experiment. Various forms of lubrication should be investigated, lemon tea, or tequila?

One or more mice came in while she was away, checked the lemon, decided it was not suitable, and left.

I'm surprised the cat didn't get them.

It did, with a squeeze of lemon.

(1) Not sure if mice have any interest in lemons as food
(2) Not everyone has cats
