According to the RAC, lack of basic car maintenance is behind half of all the breakdowns its mechanics attend. And that's because increasing numbers of us don't know how things work and that includes engines.
You can help stop the rot by buying someone the Build Your Own Internal Combustion Engine Kit.
This simplified version of a real car engine is designed to be fun to put together and to make it easier for you to understand how a full-size four-stroke car engine works.
With over 100 individual parts and all the tools you need, the kit even comes with its own Haynes Manual giving you step by step instructions to guide you through the build process. All you need to provide is the time, two batteries and a little vegetable oil.
Compared to today's multi-media uberfeast, we were positively starved of gaming entertainment in decades gone by.
So much so that in the 1980s, we were positively drooling over a certain rotund plumber with a dodgy moustache called Mario. And if we weren't zapping mushrooms with said plumber, we were pretending to be a giant monkey called Donkey Kong.
You can relive those oh so heady days of gaming nirvana wherever you happen to be thanks to the ultimate in portable gaming consoles - the new Nintendo Game Keyrings.
Styled like mini Nintendo Gameboys, each game comes on a keyring and has retractable stand on the back. Two batteries (included) are all that's needed to bring them to life.
There are three to choose from - Donkey Kong Jr, Super Mario Bros Game and Super Mario's Cement Factory Game - and they are available for £9.90 each.
