The magic dry-erase board

We have a dry-erase board on our fridge. We use this board for a running grocery list; if we run out of a staple, or are running low, we right it on the left-hand side. On the right-hand side is our running list of non-food items (like "large laundry hamper," which has been on the list for at least two years now, I think. We have this enormous wicker hamper bought from Pier One in the mid-1980s. It's kind of wearing out. But I haven't found anything similar so it's still in use).

The girls realized at some point that they could add things to our grocery list, and that we would buy them. I mean, if they got completely ridiculous we wouldn't, but I think Kiera put breakfast sausages on the list once, so I picked up a pack of Little Sizzlers and we had them for breakfast. For the most part, if they put something on the list, I will pick it up.

Right now the list says something like:

ROBOT
Cascade
cardamon pods
ROBOT
ROBOT
litter bags
lemon juice
ROBOT

Apparently Molly really wants a robot.

The funny thing is, I actually picked up a Lego Mindstorms set (v.1.0) from a garage sale last summer. (It was cheap. Much cheaper than they sell new, anyway.) It's down in the basement. Think I should bring it up and blow her mind? Or should I put it in a grocery bag and stick it in the car so it can come in like groceries after the next grocery shopping trip?
