Earth, Fire, Water and Air -- wasn't that a 70s Chicago R & B band? No, wait...that was Earth, Wind and Fire. Close enough! We love Nova Natural's Four Elements Blocks which come together to unleash your child's creativity and imagination. The blocks represent mankind's original elements: Earth, Fire, Water and Air.

These lovely German-made, non-toxic blocks are comprised from parts of Nova Natural's Wave, Rainbow, Fire and Cave tunnel set. The 20-piece set, painted with a water-based stain, is sure to keep children entertained with plenty of open-ended play.

The Four Elements block set comes in large, $109.90, and mini, $59.90.
