This is insanely clever and I imagine loads of fun! Who does not like popping bubble wrap first off, and then add paint = deal! - Bubble Wrap Stomp Painting - make some bubble wrap "boots" then dip in paint and stomp around to create art!
this looks like a great mothers day/grandparent gift/ teacher gift idea. Lots of options with flowerpots, buckets, etc to put it in and with the types of flowers or stems to use and filling in the pail.
