Team GB's Jack Laugher and Chris Mears claimed diving gold after Joe Clarke's kayak victory led a haul of medals for Great Britain in Rio.
The two golds and three bronzes in cycling, shooting and judo saw Great Britain leap from 11th to ninth place in the medals table.
Chris Mears and Jack Laugher won Olympic gold in the men's synchronised three-metres springboard final in Rio on Wednesday.
Proving the British diving team is about more than one man, the City of Leeds pair joined Tom Daley and Dan Goodfellow as medallists.
Mears and Laugher won World Championships bronze in 2015, Commonwealth gold in 2014 and European gold in May.
And now they are Olympic champions after finishing ahead of the United States' Sam Dorman and Mike Hixon in second and China's Cao Yuan and Qin Kai in bronze.
Britain's first-ever Olympic diving gold was a particularly emotional victory for Mears, the 23-year-old from Reading who had life-saving surgery to remove a spleen ruptured while diving in 2009.
Joe Clarke has won Great Britain's second gold medal of Rio 2016 by triumphing in the men's K1 canoe slalom final.
After the agony of David Florence's last-placed finish on Tuesday, British kayaker Clarke lit up a gloomy Whitewater Stadium with the race of his life.
Clarke not only won Britain's first Olympic medal in the men's K1 since Campbell Walsh at Athens 2004 but secured gold in a time of 88.53 seconds.
Sally Conway secured an unexpected bronze medal for Great Britain in the judo.
The 29-year-old from Edinburgh beat Bernadette Graf of Austria in a tense
contest in the -70kg category, securing victory with a single throw midway
through the contest.
Conway, who was knocked out at the last-16 stage in the same category at London
2012, raised her hands above her head in delight at the end.
Conway had not been tipped as a potential medallist but she began superbly with
a 57-second win over Tunisia's Houda Miled in the opening round.
The Commonwealth bronze medallist then caused a major shock by scoring an Ippon
win over world champion Gevrise Emane of France in the last 16.
Steven Scott beat his GB team mate Tim Kneale in a head-to-head contest for the bronze medal in the men's double trap.
(But luckily there doesn't seem to be any hard feelings between the pair).
Both men failed to reach the gold medal match and then faced a shoot-out with Australia's James Willett to decide which two would progress into the scrap for third.
After Willett missed out, it was a battle of the Brits to see who would take home the medal - and it was 31-year-old Scott, from Sussex, who produced the goods after beating Kneale 30-28.
