Blue Peter time capsules have really not had the best of luck over the last few years.
Filled with viewers' mementos of the time, the first one was buried by presenters Peter Purves, Valerie Singleton and John Noakes in June 1971.
The capsule, which contained photographs of the presenters and a copy of the 1970 Blue Peter annual, was dug up 20 years later.
However, it did have to be taken out early and moved elsewhere in the Blue Peter garden when its original burial site was underwent development in 1984 and they had trouble finding it again.
This started a very unfortunate trend of disasters for the Blue Peter time capsules, including them being damaged and accidentally dug up way before they were supposed to be.
Phillip Schofield and Holly Willoughby watched on in horror on this week's This Morning when one of the show's time capsules from 1981 was opened live on air - and it was carnage inside the box.
But they aren't the only ones to have fallen foul of the 'curse' that seems to have developed.

One of the most famous is the Blue Peter millennium time capsule which was buried beneath the Millennium Dome, now known as The O2, in a ceremony in June 1998.
Presenters Richard Bacon and Katy Hill put items in the capsule that had been suggested by viewers along with a Blue Peter guide, some badges and CD Rom.
The winning entries included roller blade wheels, an asthma inhaler, Tellytubby dolls, a France 1998 World Cup football, Spice Girls CD, a photo of Princess Diana, a picture of a dove to symbolise peace in Northern Ireland and a Roald Dahl book.
It was supposed to be buried until 2050, and Katy made a comment that would come back to haunt her when she said: "This one is hidden very safely underneath one of Britain's newest landmarks, the Millenium Dome."
Unfortunately, it emerged from the ground 33 years early when it was accidentally dug up by builders in 2017 while they were laying cables.
They thought they had struck gold and went at it with hammers and shovels, even damaging it with the teeth of a forklit, before realising it was actually a time capsule.
At the time, a spokesman for the O2 Arena said: "The team at The O2 and our contractors ISG have been searching for the Blue Peter time capsule since we started construction work in 2016.
"We found it yesterday but sadly it was accidently damaged during excavations. The capsule and its contents are safely stored in our office and we've let the team at Blue Peter know.
"We're going to work with them to either repair or replace the capsule and bury it again for the future."
A spokesperson for the BBC added: "Although a little earlier than anticipated, we're looking forward to sharing these memories with our viewers and making new ones as we return the capsule to the earth so that it can be reopened in 2050 as originally planned."
What was left of the time capsule was returned to Blue Peter and kept in a secret location - but the Spice Girls CD was never found.
As part Blue Peter’s 60th Birthday year, in 2018, the time capsule went on a tour of the UK to give people a chance to view the unearthed items before they were finally sealed and stored in The National Archives.
There was more chaos in 1999 when the Blue Peter team had issues trying to locate two of their time capsules.
Hundreds of viewers had written to the office from all over the world to remind the team to open the boxes originally buried in 1971.
Blue Peter editor Steve Hocking said: "I am astounded at the massive response we have had from viewers who watched the programme in 1971 who have taken the trouble to remind us to open the boxes.
"We have had some wonderfully touching letters from all over the world including Australia, Canada and Israel."
Newspaper stories that Blue Peter had lost the map proved to be untrue, although it was not very helpful and no one had any idea how deep the boxes were.
The team used a Blue Peter map and thermal imaging equipment to find the buried capsules before digging them out of the grounds of BBC Television Centre.
Now all that remains is the Diamond Time Capsule, which is safely sealed and stored in the National Archives, where it will live until 2038.
It contains a souvenir from the Royal Wedding between Prince Harry and Meghan Markle, 2018 set of UK coins and notes, a David Walliams book, fidget spinner, smartphone, World Cup 2018 sticker book and DVD of The Greatest Showman.
This comes after Phillip and Holly got a nasty surprise when they opened a Blue Peter time capsule from 40 years ago.
They had expected to find tapes of the Blue Peter theme tune, as well as clips from the show and even a script from that very day on Blue Peter
But they were gutted when the box from 1981 was cracked open and they were presented with a load of smelly brown sludge.
"I feel like a spider's going to come out of there," said the presenters as the studio descended into laughter and the camera panned to see what was inside the box.
Holly held her hand over her nose and mouth because of the smell and jokingly asked whether one of the Blue Peter dogs had put something into the box before it was closed.
Later on in the show, it was explained that the metal lining in the box had corroded and attacked everything inside, but they did manage to rescue some crisp and sweet wrappers.
