Are you a LEGO enthusiast? Many of us played with LEGOs as children and still find them entertaining today (true story: my friends and I bought and assembled some Harry Potter LEGOs and we haven’t been in LEGO’s target demographic since the late ’90s!). The Boston Public Library is hosting LEGO’s “Brick Factor” this weekend. Brick Factor is a LEGO building competition. Applications for builders are now closed, but the public is encouraged to watch the competition and cheer on their favorite LEGO master! Brick Factor takes place as the Boston Public Library located in Copley Square beginning at 10AM on Saturday and ending at 3PM on Sunday. More information can be found on the Boston Calendar.
