Area of Science:

Optics and Imaging
Astronomy Education

Background:

The camera obscura is a foundational optical device.
Pinhole optics offer a simple method for image projection.

Purpose of the Study:

To demonstrate a novel, accessible camera obscura using a common food item.
To showcase the potential of simple optics for astronomical observation, specifically the 2017 solar eclipse.

Main Methods:

Utilized a commercial snack biscuit with existing holes as the pinhole aperture.
Constructed a camera obscura-type viewer based on pinhole optics principles.

Main Results:

Successfully produced clear and interesting projected images.
The device was effectively used to observe the 2017 solar eclipse.

Conclusions:

A snack biscuit can serve as a functional pinhole aperture for a camera obscura.
This demonstrates an easy and cost-effective method for engaging with optical phenomena and solar events.
