There is a chilling story behind the ‘most dangerous object ever’ and the scientists who became its victims.
The object was made by accident and it ended up killing the people who created it.
Known as ‘demon core’, the object was repeatedly involved in two fatal accidents when scientists tested it.

The deadly item was a sphere of plutonium that was manufactured as part of the nuclear weapon development effort during World War II.
The researchers were using the plutonium to try to work out where exactly the tipping point was which would change it into an explosive reaction.
This meant that they would basically poke the core to see what reaction would happen - which you can imagine didn’t end well.
The first incident took place in 1945 when scientist Harry Daghlian was working on the core alone.
It was a complete breach of protocol for him to be alone and ended up dropping a tungsten carbide brick on top of it.
This caused it to react in a way known as ‘supercritical, which is where the core changes into an explosive nuclear chain reaction.
As a result, when Daghlian picked the brick back up, he was hit with a fatal dose of radiation.
Less than a month after this accident, Daghlian died of radiation poisoning.
While this was obviously a pretty horrific incident, teams of scientists carried on with it and in May 1946, another accident with the demon core occurred.
Involved in this one was ‘cowboy scientist’ Louis Slotin, known for being a bit risky with experiments.
On this occasion, the team were putting two beryllium dome half spheres around the plutonium core. But accidentally, the two halves were allowed to touch.
As any science buff will know, this obviously caused a reaction that made the core go supercritical.
Radiation was therefore blasted out into the room, meaning every single scientist in there got a dangerous dose.
And because Slotin was in such close proximity to the core, he did.
You won’t be surprised to know that the string of horrific accidents forced the scientific teams and institutes to urgently update their safety protocols.
Plus, in response to the fatal incidents, the ‘demon core’ ended up being melted down.
It then formed smaller cores for other bombs and missiles in the US nuclear arsenal.
But still, even now, it is regarded as the ‘most dangerous object ever’.
