Street dancer Perri Kiely secured his spot in the Splash! finals after a sensational double-dive on the ITV reality show.
The 18-year-old, best known for being thrown through the air during performances with dance troupe Diversity, soared to the top of the judges' leader board after a couple of textbook manoeuvres.
He achieved the best score of the series - 27.5 out of 30 - for his first dive from 7.5m board, and later did a running twist from 5m as all four contestants completed two descents.
Kiely, described by Olympic bronze medallist and co-host Tom Daley as the "stand out" diver in the competition, said he found it difficult diving without his high-strength spectacles.
The teenager was described as "courageous" and "fearless" by judges, with Leon Taylor saying the teenager was "a few lessons away from being a professional".
The dancer will be joined in the final by Boyzone's Keith Duffy who triumphed over wildlife presenter Michaela Strachan in a splash-off.
Really Wild Show host Strachan, who at 47 was the oldest diver left in the competition, conceded the better athlete was put through.
Earlier, model Danielle Lloyd was the first to be eliminated after leaving the judges and the voting public uninspired by her dives.
Next week's semi-finalists are Dan Osbourne, Richard Whitehead, Austin Healey and Anna Williamson.
