I remember everyone going crazy in the playground for these things. They were named 'spinners' but really they were just posh yo-yo's.
I think there were special tricks to learn such as 'walk the dog' and 'rock the cradle', and once perfected you could enter tournaments and win better versions of the spinners, such as gold ones. All this, while the other kids in the playground abandoned their elastics tournaments, lo-lo balling and Skip-its to admire your skill and panache. I like to think I'll be able to impress my own kids with the same yo-yo tricks, even if Fanta and Coca Cola Spinners aren't around anymore.
