Make S'mores Using A DIY Solar Oven

Are the sun's rays strong enough to make s'mores? Try this science experiment to find out! ​

---

What you will need: 

• An Empty Pizza Box  

• Aluminum Foil 
• A Box Cutter or Knife 
• A Marker 
• A Ruler 
• A Glue Stick 

• Plastic Cling Wrap 
• Black Construction Paper 
• Tape 

What to do: 

1. Using the ruler and marker draw a line on the top of the open side of the pizza box that is one inch from the edge of the open side of the box. Then draw two more lines on the top of the box one inch from the other open edges. Connect the three lines to make an incomplete square on the top of the box, where the side without a line is parallel to the closed edge of the box. 
   
2. ​Using the knife or box cutter, cut the top of the box along the three lines. Then fold the cut flap of the box up so the flap remains open.  
3. On the flap you just cut on the top of the box, glue a piece of aluminum foil on the side facing the inside of the box. The piece of aluminum foil should cover the entire flap.  
4. Then cut a piece of plastic cling wrap that covers the whole in the top of the box that the flap with aluminum foil was cut out of. Use the tape to seal the edges of the plastic wrap so there are no gaps between the plastic wrap and the box.  
   
5. Using the plastic wrap again, cut another piece to cover the hole in the box and tape it on the inside of the box. Now your box should have a piece of plastic wrap on the top side of the hole and on the bottom side of the hole. Again, make sure to seal the plastic wrap around the hole in the box using the tape.   
6. Now inside the box, cut another piece of aluminum foil, and glue it to the inside of the bottom of the box.  Then place your piece of black construction paper on top of the aluminum foil on the bottom of the box.  
7. Place the box outside in the sun with the aluminum foil flap propped open by your ruler and adjust the angle of the flap so that the sun shines in to the box. Leave your box in the sun for 30 minutes. Now you are ready to start making s'mores!  
   
8. At the end of your 30-minute wait place your s'mores into the box alone or on a microwave safe container. Make sure to place your s'mores in the center of the box. Leave them to cook for 15 minutes, then enjoy your treat!  

What does this experiment show us? 

• The box heats up because the aluminum foil reflects the sun's rays into the box. Then the plastic wrap traps the heat from those rays in the box making it into a homemade oven! 
• On a sunny day your homemade solar oven will reach up to 200 °F so you can heat up a variety of different treats!
