If your kids love Legos, what kids don’t love Legos? You might want to take them to the beaches of Cornwall, England, where Lego pieces continue to wash up on shore.

It’s just like collecting seashells, only you’re slipping Lego pieces into your pocket. The old Legos are from a ship that got hit by a wave in 1997. That wave knocked 62 shipping containers into the sea, including one that contained 4.8 million Legos.

Ocean currents are bringing these tiny toys to the beach, some of which have traveled as far as 62,000 miles. Then you could build a sand castle with Lego pieces as accents, maybe even enough to build a whole village in the sand.
