Question: is there such a thing as a chlorine bomb

Answer: Yes, A chlorine bomb is a small explosive device which uses the pressure of chemically produced chlorine gas or other chlorine-containing gases such as hydrogen chloride to produce an explosion. It is made with an airtight container part-filled with different types of chlorine tablet and other reagents. The reaction produces an expansive increase in pressure, eventually rupturing the container. Usually, such a device is not made on a large scale, often being manufactured from common house objects.
