E has had fun learning the concept of "sticky" this week! I taped a large piece of contact paper with the sticky side out on our sliding glass door. She loves to touch it, pat it, and pull it down (next time I'll used duct tape, so it won't come off so easily).
We put various objects and toys on it to see if they would stick. The kapla blocks stuck for hours, and clothes pins stuck for a few minutes. Larger objects didn't stick at all :) This is an activity that we will do often as I plan to show her how to put construction paper and tissue paper on the contact paper to make a collage next week.
