Cooking popcorn with your cellphoneFeatured science projectScience project video

Abstract

This science fair project was conducted to ascertain if cell phone radiation is sufficiently strong to cook popcorn. The experiment was conducted using several cell phones.

Hypothesis

Cell phone radiation contains sufficient energy to cook popcorn.

Scientific Terms

Electromagnetic radiation, microwave signals, dielectric heating, dielectric material, radiowaves

Background

Cell phone radiation

Since the cellphone became commercially available, the number of cellphone users has increased steadily year-on-year. Internationally, there are at present, over 4.3 billion users. The widespread and regular use of cell phones has raised concerns: does cell phone radiation negatively impact the health of users?

Cell phones operate on electromagnetic radiation. Such radiation is within the frequency range of microwave signals. Microwave radiation is known to cause dielectric heating. Human tissue qualifies as a dielectric material. This means that the tissue on our face will experience a slight increase in temperature when we use a cell phone. However, this increase is minimal and can be controlled by the process of blood circulation.

Some of the radio signals that are by cell phones will be absorbed by the skull. However, cell phones typically do not generate more than 4 watts of power. Thus, the power in a cellphone's signal will probably be sufficient to heat up skin and bone tissue slightly, and will probably not cause any permanent damage.
