1950s - Slinky
Slinky. Loved by kids around the world for its period of oscillation, according to Wikipedia. |
Due to the forces of gravity, a Slinky bunches up at the bottom because:
p(n) = L(n-1)^2
Fascinating! And did you know that the period of oscillation of a dangling slinky is:
T = 2/pi/sqrt{/frac{m}{k}}
Wow! Amazing! Although to be honest, that one was fairly obvious, so it probably didn't need pointed out.
You can find out many more interesting scientific facts about Slinky at Wikipedia.

1960s - Chemistry Set
Chemistry. Keeping kids entertained in the 1960s and later decades. |
The set came with an instruction manual which told you which chemicals were safe to mix together, but obviously me and my mates used to ignore the instructions, and instead we would just throw random chemicals into a test tube and see what happened. One day my parents came home to discover a pungent smell stinking out the entire the house, and apparently it turned out that me and my mates had very nearly gassed ourselves.
1970s - Skateboards
A totally rad skateboard. Gnarly! |
Since the 1970s, the popularity of skateboarding has continued to grow, with the market now worth an estimated $4.8 billion per year! If you're new to the skateboarding scene and want to fit in with all the cool kids, then try using lingo like, 'mongo-foot', 'board-slide', 'half-pipe' and 'gnarly!'. Or if you're a Wikipedia fan, then try using cool skateboard-related science terms such as, 'centripetal force', 'rotational inertia' and 'sublimated phase transition'.
Cobawunga! Or something. |
1980s - Teenage Mutant Ninja Hero Turtles
When the turtles were first released, the powers-that-be decided the word 'ninja' would transform kids into violent psychopaths, so in the UK the turtles were originally known as 'hero' turtles rather than 'ninja' turtles. Of course kids referred to them as ninja turtles anyway, and the whole thing was a bit ridiculous.
Nowadays, the powers-that-be appear to have relaxed their stance, as the ninja turtles are once again known by their original international name.
The turtles took their names from famous artists; Leonardo (Da Vinci), Michelangelo (Buonarroti), Donatello (Bardi) and Damian (Hirst).*

1990s - Who Wants To Be A Millionaire?
No coughing allowed! |
All the ingredients of the original TV show were included, and in fact the only ingredient which was missing sadly, was the million pounds. This kind of removed the excitement somewhat, but it didn't diminish demand for the game. Toys 'R' Us recently named 'Who Wants To Be A Millionaire?' as the top selling toy of 1999, suggesting it was makers Celador who wanted to be millionaires, and the success of the 'Who Wants To Be A Millionaire?' board game helped them achieve their goal.
