To use a jackhammer.
A jackhammer is a pneumatic or electromechancial tool that combines a hammer directly with a chisel. It was invented by Charles Brady King. Hand-held jackhammers are typically powered by compressed air, but some use electric motors. Larger jackhammers, such as rig mounted hammers used on construction machinery, are usually hydraulically powered. They are usually used to break up rock, pavement, and concrete. In modern terminology, a "jackhammer" does not have the capacity to drill rock. A jackhammer operates by driving an internal hammer up and down. The hammer is first driven down to strike the back of the bit and then back up to return the hammer to the original position to repeat the cycle. The bit usually recovers from the stroke by means of a spring. The effectiveness of the jackhammer is dependent on how much force is applied to the tool. In British English electromechanical ones are colloquially known as "Kangos".

Sample Sentences & Example Usage
The real questions are the ones that obtrude upon your consciousness whether you like it or not, the ones that make your mind start vibrating like a jackhammer, the ones that you "come to terms with" only to discover that they are still there. The real questions refuse to be placated. They barge into your life at the times when it seems most important for them to stay away. They are the questions asked most frequently and answered most inadequately, the ones that reveal their true natures slowly, reluctantly, most often against your will.
