Foam!

Last week, when I wasn't feeling well, I needed to come up with activities for the girls that would keep them entertained without too much effort on my part. So, one day I spread out their messy tablecloth (aka vinyl shower curtain) and covered it with shaving cream.

They built foam castles, plowed plastic boats through it, scooped it around with cups, wrote letters in it, and mostly just smashed it around with their hands. It took about 30 seconds of set up, 3 minutes of clean up, cost under $2, and bought me about 45 minutes of happily entertained girls - success!
