Fact #2 - TNT and dynamite are not the same thing at all, contrary to what the Road Runner and Wiley coyote would have you believe. Dynamite doesn’t actually contain TNT, but rather is comprised of an absorbent mixture soaked in nitroglycerin, which is extremely sensitive to shock, unlike TNT; this is then wrapped in paper and voila, dynamite. The top picture shows a clock which can be set on a TNT explosive and can detonate like dynamite.
