NOW here’s one that teenagers and dads will want on their Christmas lists.

Nanodots blur the lines of science, education and obsession, stimulating your competitive side while challenging your patience.

These little metal dots are made out of the strongest magnets known to man and can lift 1,000 times their own weight.

News Shopper has teamed up with the makers to give away eight sets of 125 Galaxy Black and 125 Nanodots, worth £29.49 each, plus a splitter pack worth £9.99, to help with building techniques.

The Nanodots come in seven colours and take construction toys into the 21st century, with the possibilities for what you can build limited only by your imagination and perseverance.

Big Ben, the Empire State Building, the Arc de Triomphe and, more recently, Harrods are some of the landmarks re-created so far.

For most, mastering the 64 dot cube is testing enough.

You can learn all the tricks and techniques at dotpedia.com and thenanodots.com to get you going once you have purchased your Nanodots from Maplin or MenKind.

To be in with a chance of winning one of eight sets of Nanodots kit, all you have to do is answer this simple question:

How many different colours of Nandots are available to buy?

A) 1
