PVC Sprinkler Water Toy - how smart is this? 10 bucks worth of materials from the hardware store will bring lots of joy this summer. :) TWIST use a couple of pipes and plastic streamers as well, call it a "car wash" and ride bikes through it.
A lego wall. Add this to my fun wall ideas. So one wall will have chalkboard paint, another dry erase, now a lego wall. Now I just need a felt wall for felt play and a magnetic wall. I saw this neat project somewhere about a ball track on a magnet wall.
