Heather Lewinton has raised £515 for Peace Hospice Care after jumping 13,000 feet out of a plane.
The 24-year-old from north Watford did the skydive in memory of her aunt who died at the hospice two years ago.
Heather, of Eastfield Avenue, said: "The last thing you would think of me is 'adrenaline junkie'.
"But it was amazing - I loved it. When I finally came back to earth, my stomach was still in the air.
"As it stands it's raised £515 for the Peace Hospice, well past my goal of £400."
The graphic designer and marketing assistant's skydive can be seen on her YouTube channel Heather Lewinton.
