These five massive, 6-foot water platters really float!  They have been installed in ponds and lakes around the world, and gently drift in the wind.

Building them

They are huge! Each took over 60 hours to build, after weeks of experimenting with various materials that would allow the 200-pound sculptures to delicately float.

Here, Eun Nye, Jung Ah, and Ji Yoon build the first water platter using over 10,000 LEGO pieces.
