The marble thing

The little kid is playing with this tube and marble thing.  She wants me to help her construct the tube, then she’ll place the marble in one of the tubes and sees where it ends up.    I put a tube on; she takes it off.   I try to put a marble in and she takes it from me.  

It’s ok, though.   Her tubes are well-built.   Sometimes my marble just disappears.  🙂
