Did you ever spend hours as a kid assembling a LEGO masterpiece only to have one of your siblings come along and destroy it? Well that never would have happened if you had constructed it from these concrete building blocks which resemble, but are in no way officially licensed by, LEGO. In fact, while they might look exactly like your standard 2×4 LEGO building block, they actually appear to be just slightly larger. And I doubt they feature the cutout on the bottom allowing the pieces to stack and connect. So you’ll also need a small trowel and a cup of mortar to keep your creations together.
