Hours before his 13th birthday, Jackson Oswalt (USA) fused together two deuterium atoms using a reactor he had built in the playroom of his family home in Memphis, Tennessee. This incredible feat has led him to be one of the stars of this year’s Guinness World Records 2021 edition, alongside other record holders. Now, at 15 years old, Jackson no longer conducts experiments that often, as he’s decided to look for his "next best thing".
