I found this on Family Fun and think it's awesome! We're doing it tomorrow! This would be a fun and cheap thing to do for a playdate or for any day that you want to jazz up lunch. :)
1. Fill each paper cup with two tbsp. of milk. Add a few drops of food coloring to each cup.
2. Paint pictures and designs on the bread using the colored milk and new paintbrushes.
3. Toast lightly and use the slices to make crazy sandwiches.
