Which puddles make the best mirrors? You can take a walk outside after it rains to find out, or you can make your own puddle inside.

What You Need

• Small bowl
• Black construction paper
• Rubber band

What You Do

1. Line Bowl with Paper
   Arrange the piece of construction paper so it lines the bowl. Secure it with a rubber band.
2. Fill Bowl with Water
   Fill the bowl with water. Put the bowl on a larger plate so your table doesn’t get wet. (The water soaks through to the edges of the paper.)
3. Test Out Your Mirror
   Your water mirror will only reflect if you have a source of bright light. Try going outside or standing by a window on a sunny day. Move around until you can see yourself in the water.
