The first Tuesday of every month Lego stores offer a free mini-build for kids age 6-14. Starting at 5pm, while supplies last, kids will be able to build a small Lego creation and bring it home. Word on the street is that kids don’t have to strictly follow instructions while building the model. The next build is May 5, 2015. The project is this koala. You can find the LEGO Store at Concord Mills.
