Choosing the Right Materials
Selecting the appropriate materials is crucial for constructing a successful eclipse viewing box. Here are the key factors to consider:
1. Box Frame
The frame of the box should be sturdy enough to withstand the weight of the solar filter and provide a stable base for viewing the eclipse. Consider using lightweight yet durable materials such as aluminum foil, cardboard, or a stiff piece of black paperboard. Cardboard is a great option for both its sturdiness and ability to block out sunlight.
The size of the box will determine the viewing area, so it should be large enough to comfortably fit your head and allow you to move your eyes around to observe the eclipse. A box measuring approximately 12x12x12 inches is a good starting point.
| Material | Advantages | Disadvantages |
|---|---|---|
| Aluminum Foil | Lightweight, reflective, and easy to shape | Can be flimsy and may require reinforcement |
| Cardboard | Strong, durable, and blocks light well | Can be heavy and difficult to cut precisely |
| Black Paperboard | Dark, rigid, and inexpensive | May not be as durable as other materials |
Constructing the Box Frame
Materials:
- 4 pieces of cardboard, each measuring 12 inches by 8 inches
- Scissors
- Ruler or measuring tape
- Glue or tape
- Aluminum foil
- Black construction paper
Instructions:
-
Cut out the four pieces of cardboard to the desired size.
-
Assemble the box frame by gluing or taping the four pieces of cardboard together along the edges to form a rectangular frame.
-
Reinforcing the Frame: To provide additional stability and support to the frame:
- Apply a second layer of cardboard to the inside or outside of the frame, gluing or taping it in place.
- Insert cardboard strips or dividers inside the frame to create compartments or sections that will help keep the viewing screen in place.
- Use strong adhesive tape to reinforce the corners and edges of the frame, preventing it from warping or collapsing during use.
- Consider using a rigid material, such as foam board, for the frame instead of cardboard for increased durability.
-
Cover the inside of the box frame with aluminum foil. This will act as a reflective surface to enhance the brightness and clarity of the image projected onto the viewing screen.
-
Cover the outside of the box frame with black construction paper. This will help block out stray light and minimize glare, ensuring a clearer and more focused viewing experience.

Lining the Box with Reflective Material
To enhance the visibility of the solar image projected onto the screen, the interior of the viewing box needs to be lined with a reflective material. This material helps redirect the light from the Sun towards the screen, providing a brighter and clearer image.
There are several suitable materials that can be used for lining the box, including:
- Aluminum foil
- Mylar
- White cardboard
Of these options, aluminum foil and Mylar are particularly effective due to their highly reflective surfaces. White cardboard provides a decent level of reflectivity but is not as efficient as aluminum foil or Mylar.
| Material | Reflectivity |
|---|---|
| Aluminum foil | High |
| Mylar | High |
| White cardboard | Moderate |
When choosing a material, consider the size and shape of the box and the availability of the material. Ensure that the material is cut accurately and fits snugly within the box, extending from the back of the box to the front where the screen will be placed.
To secure the material in place, use adhesive tape or glue. Avoid using any materials that could create reflections or glare, such as shiny tape or glossy paper.
Creating a Solar Filter
To create a safe solar filter for your eclipse viewing box, you will need the following materials:
- Aluminum foil
- Scissors
- Tape
- Cardboard
- Black construction paper
- White printer paper
- Plastic wrap
Instructions:
1. Cut a piece of aluminum foil large enough to cover the front of your eclipse viewing box.
2. Tape the aluminum foil to the front of the box, making sure that it is smooth and taut.
3. Cut a piece of black construction paper slightly smaller than the aluminum foil.
4. Tape the black construction paper over the aluminum foil, centering it as much as possible.
5. Cut a piece of white printer paper slightly smaller than the black construction paper.
6. Tape the white printer paper to the black construction paper.
7. Cut a piece of plastic wrap slightly larger than the printer paper.
8. Tape the plastic wrap over the printer paper.
Your solar filter is now complete. Be sure to test it out before the eclipse by looking at the sun through it. You should not be able to see any direct sunlight through the filter.
Attaching the Solar Filter to the Box
Step 5: Carefully Attach the Filter
Once the filter has been cut to size, it’s crucial to attach it to the front of the box with utmost care. This step requires precision and delicate handling to ensure the filter’s effectiveness and alignment:
- Position Carefully: Ensure the filter is placed evenly over the aperture, covering it completely without any gaps or overlaps.
- Use a Thin Adhesive: Opt for a narrow strip of clear or black adhesive, preferably around 1/16 inch wide, to attach the filter to the box. This minimizes potential distortion and ensures a secure hold.
- Apply Sparingly: Use minimal adhesive to avoid any wrinkles or bubbles on the filter. Apply it evenly along the edges, taking care not to cover the viewing area.
- Secure Tightly: Press the filter firmly against the box while the adhesive sets. Avoid excessive pressure that could damage the filter or distort the viewing image.
- Protect from Damage: Once the filter is secured, cover it with a thin protective sheet or cardboard to prevent accidental scratches or damage during storage or handling.
Tip: For a more secure and durable attachment, consider using a heat-resistant adhesive or double-sided tape specifically designed for solar filters.
| Adhesive Type | Pros | Cons |
|---|---|---|
| Clear Adhesive | Invisible bonding, no distortion | May yellow over time |
| Black Adhesive | Blocks stray light, enhances contrast | Leaves a visible bond |
| Heat-Resistant Adhesive | Withstands high temperatures | May be difficult to remove |
