An assassin was hired to place poison in the cooking oil in Mc Donald Frying machines. When the worker checks the machine, he notices a powder floating in the solution and spoils the assassin's plans. Why did the assassin's plans get spoiled?

The poison (powder) was a polar molecule and, therefore, won't dissolve in the non-polar oil.
