Using Oreos to Block Microwave Radiation

Contributors: Jacob Tynan

 

EXPERIMENT:

  • To study the effectiveness of Oreos to shield a beaker of water from the effects of microwave radiation emitted from a household microwave.

MATERIALS:

  • 9 25 mL glass beakers
  • 45 Oreo Cookies
  • Thermometer
  • Microwave

PROCEDURE:

  1. Place a 25 mL beaker of water into a microwave for 1 minute and immediately measure the temperature thereafter. Perform three times.
  2. Place a 25 mL beaker of water into a microwave and surround it with one layer of Oreos (5 Oreos). Cook for 1 minute and measure the temperature immediately thereafter. Perform three times.
  3. Place a 25 mL beaker of water into a microwave and surround it with two layers of Oreos (10 Oreos). Cook for 1 minute and measure the temperature immediately thereafter. Perform three times.

DATA:

  • Data table 1 shows notes and data collected for three tests.
    Number of layers 1 layer 2 layers 3 layers
    Average ending temperature (°C) 67.2 66.7 89.03
    Notes 20 mL evaporated 20 mL evaporated 5.83 mL evaporated

RESULTS:

  • When two layers of Oreos were placed around the beaker, a substantial amount of water remained liquid, unlike the water in the previous tests: therefore, an effective radiation shield can be made of Oreos, at least for the time used in the experience.
  • If the microwave had been set to 2 or 3 minutes, then the water would have been completely evaporated and the Oreos would have been reduced to unrecognizable mush. Hence, an Oreo radiation shield placed on the sides of the International Space Station would most likely be grossly ineffective.

POSSIBLE APPLICATIONS:

  • Could use microwaves to make Oreos very mushy and stinky, if you're into that kind of cookie.
  • Could protect one's self from high radioactivity for a very short amount of time.
