I'm always searching for new ways to play with Grant and I found this idea on Pinterest.com I was worried that I was going to go through the time and money for Grant to take one glance at it and run on by to something more interesting. Surprisingly he loves it! He can turn, spin, flip, slide, open, twist, lock, push, etc. Lots to keep him busy and figuring out. It cost about $30 to put together because we only had the lock and combination lock in our home. But if you search your house you may find all sorts of things you can use and bring the cost down even more.
