Safety was a concern at home

A seventh-grade student from the Dallas school district, Aiden McMillan, successfully produced nuclear fusion at the age of 12, after four years of studies, prototypes, and tests. The project, started when he was just 8 years old, is now gaining national attention and could lead him to the Guinness as the youngest person to achieve the feat.

Project started when Aiden was 8 years old

Aiden McMillan spent two years studying nuclear physics concepts before starting to assemble the first prototypes of his machine.

According to the consulted material, the construction took another two years and involved trial, error, persistence, and problem-solving.

The student stated that the project was born out of curiosity and personal interest. He said that the experience did not bring direct benefit to his routine, but it connects to what he considers to be the energy of the future.

Nuclear fusion machine inspired creation space in West Dallas

McMillan’s work helped inspire the Launchpad, a nonprofit creation space aimed at students.

The location operates in a brick building in West Dallas and was partly created to support ambitious projects like his.

The purpose of the space is to offer support to young people interested in developing more complex scientific and technological ideas, like the nuclear fusion machine built by the student.

Safety was a concern at home

During the process, safety also became a central topic in family conversations. McMillan mentioned that his mother was quite worried and asked him to explain what could go wrong, how it could happen, and how to avoid risks.

The concern accompanied the long construction phase, marked by adjustments and difficulties. The student himself summarized the experience by saying he loved the project but also came to “kind of hate it.”

Milestone was reached after four years of work

After four years, McMillan achieved the expected result: he produced nuclear fusion and detected neutrons.

Commenting on the moment, he said he was emotional, describing the achievement as the end of a long journey.

Now, the feat puts the Dallas student in pursuit of recognition by Guinness as the youngest person to achieve nuclear fusion.

This article was prepared based on the information provided in the source material about Aiden McMillan, Dallas ISD, and Launchpad, with data, numbers, and statements preserved as per the consulted material.
