If you have any experience with LEGOs, you'll know that these things are the epitome of "do it yourself." The whole idea is that you use these building blocks to craft buildings and structures. But it seems as though this person decided to try something new and different. Instead of slotting them all together, they decided to shove them into a bottle and fill it with soap. Why? Well, we're not sure.
Of course, a child might appreciate this when they begrudgingly wash their hands before dinner. And at least these LEGOs aren't on the floor for you to impale yourself on, right?
