Great fun for the youngsters!
If you have kids this is the one to take them to. If you don't, to be honest I wouldn't bother.
It's like a sort of mini-Disney attraction. If you are five years of age it may be the most thrilling thing you have ever seen. My son used to love it and it was worth going just to keep him happy. On that basis, adults will not be disappointed. If you expect it to be a sophisticated all-singing, all-dancing attraction to keep people over the age of 14 amused, then forget it.
For what it does, it does well though. Dynamic Earth takes you on a journey through our planet’s past, present and future, with interactive exhibits including some animatronics and special effects, both 3D and 4D. The final part is a planetarium, which is fun and very effective.
If you are in crowd of adults and kids I would get a couple of adults to herd the kids in to Dynamic Earth whilst the rest of you go and see The Scottish Parliament or Holyrood Palace just next door.
