Blurring the lines of science, education and obsession, Nanodots are the latest toy for teenagers and adults that will stimulate your competitive side whilst challenging your patience.

Made out of the strongest permanent magnets known to man, built to lift 1,000 times their own weight and available to buy in seven different colours, Nanodots are the addictive micro magnets which take construction toys into the 21st century. The possibilities of what to build are endless, making the only limitations how far your imagination and tolerance can stretch!

Big Ben, the Empire State Building, the Arc de Triomphe and more recently the iconic Harrods building are just some of the impressive landmarks which have been constructed so far, although mastering the 64 dot cube is testing enough for most. To learn all the tricks and techniques, and to view these mind-blowing creations and more, visit the www.dotpedia.com and www.thenanodots.uk.com websites.
