I can't remember all the text but here is my trial activity! I saw it with contact paper but didn't have any so I looped packing tape on itself
Loop packing or masking tape in loops and affix to a kid height surface.
Add objects to stick to it- I did a spoon, lid, funnel, cotton balls, and cotton swabs.
Good/bad: LO (14m) was amused! He liked the q tips standing straight up and trying to pluck them off. After about a minute he was more comfortable and messed with the tape itself.
Only downside was I had to confiscate the cotton balls; he seemed inclined to tasting them!
I might try this on the patio window, too.
