In order to build a nuclear reactor like that, you must possess a number of dangerous radioactive materials. Uranium, barium sulfate, americium, they’re all radioactive elements you wouldn’t expect a Boy Scout to possess. You would expect that he had to go to great lengths to obtain these materials.
Nothing turned out to be farther from the truth. Without too much effort, David managed to gather the raw materials he needed for his extreme chemistry project. After the ensuing fiasco, the US government became a lot more vigilant when it comes to these kinds of materials, especially with regard to potential terrorists.
Curious how he got the radioactive material? Read on quick!
