Party Favors
Send the kids home with their own black bat capes and masks. Cut out large rectangles from black non-fraying fabric and tie two corners together. As the kids depart, face paint a mask on each of their faces with black paint.
Make sure to send a Batman thank you note to your party guests. Include a keepsake photo of each child in the giant bubble and write on the photo, “I survived the Mr. Freeze Bubble at ______’s Birthday!”
