What You’ll Need- White tempera paint- Tacky glue- Paper cup- Freezer paperWhat to Do1. Mix equal parts tempera paint and tacky glue in a paper cup. 2. To create “spilled milk,” slowly pour most of the mixture onto freezer paper. 3. Lay the cup on the edge of the puddle. Add a slightly crumbled cookie. 4. Let it dry for two days. Extend the FunFor younger kids: Talk about other “spills” you might come across: a puddle of paint, a melted ice-cream cone, a cup of juice. (Kids being kids, they’ll probably bring up their own gross favorites: pet stains anyone?) See how many you can think up and what’s different about each spill. For older kids: Replicate some of the spills imagined above by substituting colored paint for white paint and mixing it with the tacky glue. Have your kids place the replications around your house or school to startle teachers, siblings, and friends.
