Losing my marbles

Wow.  Grace has grown up so much in one week of kindergarten.  She won't tell me much about school.  Some days she tells me I am allowed to ask only two questions.  (That is bad when I waste one on a question like, "Why is your glue still in your backpack?")  Some days she makes up funny stories about what happened in her class.  And some days - if I get lucky - she actually tells me a tiny bit of something about her day.  A couple of days this week she was playing with wooden blocks with grooves in them when I picked her up.  You build a contraption and then race marbles down.  This is a new interest for her.  I like the open-ended play and that she has to figure out how to make the marble run work.  And, since we didn't have anything like that in our house, I did some research and found this awesome Quadrilla set at a local toy store. Right after school today we built this twisting tower together.

The only problem is that there are marbles rolling all over the floor.  The set comes with about 30 of them and Grace wants them ALL to roll in her tower at once!
