Children work together to make things out of the large, interesting shapes. There are pipes and wheels, blocks and gears. Possibilities are limitless; make a house you can climb in, a space ship, or a car. Parents are welcome to help small children assemble the large pieces, which are light and soft to prevent injury. This is a fun place to use the imagination. Being indoors, it is also a good choice for inclement weather.
