What you need:
- aluminum foil
- two 12-ounce cups
- black construction paper
- 2 Hershey's kisses
- graham cracker
What to do:
- Make two kinds of ovens:
- Cut a 7" x 7" square of aluminum foil.
- Place it shiny-side up and fold the foil diagonally to make a triangle. Unfold the foil and repeat with the remaining two corners.
- Gently stuff the foil, shiny-side up, 2 1/2" into the cup, so you have a cone-shaped bowl.
- Tape the bowl to the cup.
- Repeat steps 1-4 with black construction paper.
- Make hot fudge!
- The parent should hold both ovens so that they face the sun. Make sure there are no shadows!
- Using foil, cut a tiny "plate" for your chocolate. Place the plate on the bottom of the foil oven.
- Using black construction paper instead of foil, repeat step 2 for the paper oven.
- Set a piece of chocolate on each plate.
- Ask your child which piece of chocolate she thinks will melt first. Then have her observe which piece gets shiny first.
- After two minutes, poke a toothpick into each piece. Which is softer? Which melts first?
- Spread the gooey chocolate on a graham cracker for a tasty treat!
