Every month Lego stores worldwide host free build sessions for children aged between 6 and 14. The sessions are free to attend, you don't book in advance (although each store only gets a certain amount) and best of all, the kids get to take their free Lego creations home with them.
The free build sessions usually take place after school on the first Thursday of every month, between 4pm and 6pm. At every session, the children are given a new model to build. This month was a hovercraft; last month it was a helicopter.
You can see all the previous mini models on their Mini Builds page along with instructions to build your own if you do not live near a LEGO store.
In the UK, Lego has stores at Bluewater, Brighton, Cardiff, Glasgow, Leeds, Liverpool, London Stratford, London Westfield, Manchester, Milton Keynes, Newcastle, Sheffield and Watford. Click here to see the store details.
