Apparent 'violations' of natural laws are easy to contrive if you ignore the restrictions on the data that the law is based on.
For example, Charles' law states that volume is proportional to temperature for a fixed number of moles of ideal gas at fixed pressure. Charles' law is usually applied as an equation:
Notice that the restriction isn't included in the equation. Unfortunately, that causes some people forget all about restrictions when applying a law in equation form. Could you safely use Charles' Law to predict the temperature of the CO2 trapped in the neck of a soda bottle, after you pop the top, given its initial temperature and its initial and final volumes? Could you use Charles' Law to predict the final volume of 1L of water heated from 0°C to 100°C?
When experimental fact is in conflict with a law, the law must be either corrected or discarded. This is a rare occurrence, because laws must summarize a large body of experimental data before they're elevated to law status. But it does happen. For example:
