Lego refrigerator magnets

Step 2 Put the magnets in the Lego brick

You don't need to glue the magnets into the Lego brick. I did on a few and found that the magnets stay just fine without it. A little drop inside the round cylinder part of the Lego brick will guarantee they will stay in though. Once again, stacking two makes them nice and strong. By putting the magnet inside the cylinder the Lego can still be attached to other bricks (either ones with magnets or those without).
