Last time I was at Ikea I picked up a bead roller coaster. Its been sitting in the closet waiting for Marshall to grow into. On a whim I decided to pull it out.

Then I showed him how to slide the beads around and after a lot of concentration, he picked it right up!
And now we have a new favorite toy!
