:00:00. > :00:11.With summer holidays on the horizon, we ask where you guys like to go.
:00:12. > :00:26.Find out what causes this amazing sight.
:00:27. > :00:35.First this morning, Liam Payne, Rita Ora, Stormzy and Leona Lewis -
:00:36. > :00:50.# Like a bridge over troubled water... #
:00:51. > :00:53.Just a few of the names who are helping to raise
:00:54. > :00:55.money for those affected by the Grenfell Tower fire
:00:56. > :00:57.The singers recorded Bridge Over Troubled Water
:00:58. > :01:01.The song hit the number one spot on iTunes just two hours
:01:02. > :01:04.The X Factor judge Simon Cowell organised the track.
:01:05. > :01:07.I was thinking at the time, raise some money, I also
:01:08. > :01:09.thought raise awareness, and I also thought
:01:10. > :01:13.I wanted it to be something that, you know, weeks, months later,
:01:14. > :01:19.when you hear the record, you still remember what happened.
:01:20. > :01:22.Next, to something that looks like it's from out of this world -
:01:23. > :01:34.It's a rare sight, the ocean glowing in the dark.
:01:35. > :01:36.Yeah, a couple of salmon at the back jumping out.
:01:37. > :01:38.It was like fireworks sort of thing, the water.
:01:39. > :01:43.What you're looking at is Noctiluca scintillansmore, also
:01:44. > :01:47.When you pick it up, it dribbles through your fingers.
:01:48. > :01:49.Whenever it lands on something, it glows.
:01:50. > :01:53.Just little splatters of bright blue, I suppose.
:01:54. > :01:56.The glow is caused by a natural chemical reaction with algae.
:01:57. > :01:59.When a boat drives through it or you put your hand through it,
:02:00. > :02:02.the chemical reaction is initiated, as a result of which,
:02:03. > :02:11.Algae are tiny living things that are found in water all the world.
:02:12. > :02:14.When the algae is touched, it changes colour from a dull pink
:02:15. > :02:23.They are not observed as often in the colder waters off Australia
:02:24. > :02:25.but more in the sub tropical and warm temperate waters.
:02:26. > :02:29.This display was caught on camera at a beach in South Australia.
:02:30. > :02:38.The glow is completely harmless, but what a sight!
:02:39. > :02:42.It's getting nearer to that time of year when some of you will be
:02:43. > :02:44.packing your bags and heading off on your summer holidays.
:02:45. > :02:47.But when it comes to destination, do you prefer to visit somewhere
:02:48. > :02:49.you already know or go to somewhere new?
:02:50. > :02:54.So, everyone loves a new adventure once in a while, right?
:02:55. > :02:59.And with the summer holidays soon approaching, I think you're dreaming
:03:00. > :03:02.of that new and exciting destination you could possibly visit to create
:03:03. > :03:08.But did you know that one guy believes it's less
:03:09. > :03:14.about where you go and more about where you go back to.
:03:15. > :03:22.I think, as a child, what you really want
:03:23. > :03:27.when you are small is predictability in your holiday destinations.
:03:28. > :03:29.Your parents may want to drag you around churches and art
:03:30. > :03:31.galleries, but is that what you really want?
:03:32. > :03:38.What you want is the same beach, the same hills, the same rivers,
:03:39. > :03:43.When you are ten, you really couldn't care less whether you are
:03:44. > :03:47.Thanks, Dr James, but how many of you agree with his theory?
:03:48. > :03:50.I don't really agree with Dr James's statement.
:03:51. > :03:55.I've been to a few places on holiday.
:03:56. > :04:02.I think it's best if you travel when you are younger
:04:03. > :04:06.I like going to the same place every year.
:04:07. > :04:08.I think it is nice to go somewhere new after a bit,
:04:09. > :04:11.but it's just relaxing to go to the same place,
:04:12. > :04:15.So, I've been going to Italy for the past two years,
:04:16. > :04:21.but before that, I've been going to Cyprus for nine years.
:04:22. > :04:23.My parents and my grandparents own a little caravan
:04:24. > :04:26.in North Wales and I've been going there since I was
:04:27. > :04:33.I personally like going different places because it's good to get
:04:34. > :04:36.new experiences and enjoy going somewhere new.
:04:37. > :04:45.Well, whatever the case may be, as long as the sun's out, I'm happy.
:04:46. > :04:54.Newsround's back right here in about half an hour.
:04:55. > :05:07.Look online to see the other stories around today. See you soon.
:05:08. > :05:08.Good morning, you're watching CBBC HQ.
:05:09. > :05:12.Welcome to the start of a glorious Thursday!
