The catch the bullet trick is known by most magicians to be the most dangerous trick of all time. It should not be denied that a bullet can obviously kill and it can kill fast. This is one trick that a lot of magicians have tried doing and most of them have died trying it. The moment that something goes wrong, expect that it can lead to serious complications.
Aside from this though, there are still other tricks that are not very safe but are still being done by magicians. There are reports of stunts going horribly wrong even though it was practiced and all of the details were supposedly planned ahead of time
