Forts are very magical spaces that afford the opportunity for play, social-emotional practice, and creativity. Forts are best built by using found objects such as sticks and leaves, but for city dwellers or those who need a tidier option Crazy Forts are the way to go! Crazy forts are plastic sticks that you can join together with a rubber connector ball to engineer forts you can easily throw a light blanket or sheet over to create a super secret space of you liking.

The first time I saw anything in the realm of pre-made fort materials was at the SITU Studio - Student Program - New York Hall of Science Design Lab where they had sticks of varying sizes and rubber bands to connect them.
