Lego Ice Cube Bricks Tray
Make your own limitless supply of Lego ice cube bricks! You might not be able to build a house out of them before they melt, but they'll look awesome in your drink!
Even better, they won't hurt your feet in the middle of the night. Although, we suppose you could slip on the melted water and hurt your back or something.
Note that is is not officially licensed by Lego, so the quality of your ice bricks is in doubt. We doubt you care about that though, as you just want cool looking ice cubes.
You could also use these for fondant or molding chocolate!
