Another weird photo. Does the camera lie ?

Another distorted photo. This time of childs hand. Shared with me this week...

How strong ? !

So in a period of 24 hours a new pipes stop tap has been turned off  twice by an unknown force. It begs the question how much strength or torque can an unseen force muster up ? Ive previously come across two bolts with self locking nuts that had unwound themselves. That requires some real force, a lot more than moving say house hold objects.
