The Law of automatic adhesion and magnification
Any drop of water left on the kitchen counter will automatically attach itself to the first vessel placed on the counter and proceed to grow and drip all the way from the counter to wherever the vessel is being carried.
Corollary: The Law of Sindbad
The same drop of water, when faced with a wiping sponge, will escape the said sponge like Sindbad escapes the Roc birds in the valley of diamonds.
