Review on Wooden Puzzle Kits Engineering Functioning by Dusty Oner

This thing is very cool. The kids enjoyed it very much. This is a good alternative to pad forts, which don't let much air through and get warm after a few minutes of play. My only very minor complaint is that it's so light it floats easily in the air with a fan breeze. While the floating forts are admittedly pretty cool, we decided to attach them to a slab "floor" and leave them on solid ground. A few small weights on the bottom seam would have improved the design, but overall we're happy with this purchase.
