STEM Builder Series Build a Waterway

My 4-year-old has spent hours figuring out how to tilt the pieces just right to keep the water flowing. The 90 pieces give plenty of room for trial and error without being overwhelming. It's been a great way to introduce basic physics concepts through play.

We've had this kit for a week and my 5-year-old is already fascinated by how adjusting the slope changes the water flow. The 90 pieces give him enough to build a really complex system on his own.

My 4-year-old kept rebuilding the ramps to see if the water would go faster, and the 90 pieces gave us hours of trial and error. The gravity experiments were simple enough for her to understand on her own, which made it feel less like a toy and more like her first real engineering project.
