I love this activity because it's the easiest thing to pull out after dinner or on a rainy day and keeps O entertained and imagining for a surprisingly long time. Just use painter's tape, which peels off easily without leaving a mark. You can also create your city on a yoga mat.
Our creation of a tape city always begins with a parking lot.
How We Did It
Next O decided we needed a REALLY long highway.
Then he created an aquarium and lake.
I thought the 3-D waterfall (an accidental discovery) was a nice touch.
Our complete city! We could have kept going all night but were thwarted by bath time.
