Scientists in Oxford have got their hands on the Crown Jewels – by making their own. Physicists at Oxford University’s crystal growth unit grew a replica of the Imperial State Crown, part of the famous jewels held in the Tower of London. They also managed to reproduce the Duchess of Cambridge’s engagement ring from common household items including drain unblocker, sandpaper and antiseptic cream.
They will be displayed at the Big Bang UK Young Scientists and Engineers Fair at Birmingham NEC, March 11th to 14th
