Do the Ziploc bags filled halfway with water and a penny really keep the flies away and why?

Answer:

Water, Ziploc Bags, Pennies, and Flies

  • The common house fly has a morbid fear of drowning and is somewhat claustrophobic so goes out of its way to avoid enclosed bodies of water.
  • MythBuster: Actually, this is a domestic legend-- flies are not repelled by any type of water, regardless of whether it contains pennies. The best way to repel flies and bees is to get an orange wiffle bat out of the garage and swing away or use pesticides.
  • Its the reflection of the penny that keeps them away, it appears to be a predator.
  • No a ziplock baggy filled with water in it does not keep the flies away, but putting a penny in it does the trick.
 

One User tested out the theory:(FYI this is all in Jest)

THEORY: Placing Zip-Lock bags of water on the wall repels flies.
COLLECTIVE SUMMARY:

Makes you wonder how someone figured this technique out. The comment about the molecules of water having their own individual prism and the disco ball effect is not valid. Water would have to be in vapor form to have individual prisms, and because of distance from light source, would have identical photonic paths, and would produce no more than a shimmering effect, far too slow to cause any disorientation in a fly.

My hypothesis of this effect is that pennies in water will ionize (emit electrons), especially if there is trace sodium (salt) or other ionizing element in the water, thereby generating a electromagnetic field that produces a sine-wave/frequency based on ambient temperature; as the temperature of the water reaches optimal range (90 degrees or more), the frequency begins to match the resonant frequency of a fly's skull, effectively 'ringing' it's neural center-mass like a minuscule bell.

To test this hypothesis, I am nailing hundreds of bags of water with pennies to my walls in anticipation of flies simply falling dead in the air.

(Autopsies will be forthcoming. I will report results of this experiment at it's conclusion.
Thank you for your patience)

RESULTS OF TEST

As I tested my hypothesis, I discovered that having more than one bag in a room cancels out the effect, unless the ionization is synchronized prior to deployment. This is accomplished using the following procedures.

1. Each bag should have an odd number of pennies, but more than one. (see note 6 for detail) The pennies are not for ballast, because the water has enough mass to keep the bag behaving as per Newton's 'local cluster' theory of Gravity. Anything more than 5 pennies produces diminishing effects.

2. Pennies should be soaked in 2 parts Vinegar to 5 parts distilled water for 48 hours, then rubbed with salt for 2 minutes on the heads side, and 3 minutes on the tails side.

3. Pennies should be stacked and remain in contact with each other for another 24 hours, to synchronize electron frequencies.

4. Size of bag has no amplification effect; a sandwich bag is sufficient. 30 Gallon Garbage bags demonstrated no additional range or amplitude in effect.

5. IMPORTANT! The bag should be placed where it will be exposed to direct sunlight for no less than 1 hour, and no more than 4 hours. On rainy/cloudy days, hand-warming of bags will be sufficient to sustain 50% effectiveness.

6. The penny issue dates are inconsequential, but should be after 1958. 1934-1936 issued pennies work also. Pennies minted in different regions of the country and at different years will have solidified under different geomagnetic influences, which enhances the physiomolecular generation of an electromagnetic field. To avoid the canceling out of ionic emission frequencies, an odd number of pennies is necessary.

In addition:

7. Because effectiveness is based on the reflective properties of the walls and furniture, a test group of flies in the room are necessary to determine optimal placement of bags. The placement of bags will create fly 'kill zones' of about .5 cubic meters. When placing additional bags, observation of the flies are critical in determining optimal placement. Auditory observation is sufficient; a fly will let out a audible 'yelp' when it enters a 'kill zone' before falling to the ground in mortal seizure.

8. Ensure the fly is dead prior to handling; if only stunned, the fly may become aggressive and dangerous when recovered.

9. On a periodic basis, relocate bags in room; flies may learn kill-zones over time and avoid.

10. Effect may 'leak' out of room into adjacent living areas. Ensure your neighbors are aware of your effort to avoid 'flyslaughter' litigation.

11. As always, use safety goggles and knee/elbow pads, and OSHA approved safety gear when conducting setup and maintenance.

12. Contact your local Community Services division to determine any City, County or State ordinance prohibiting/restricting construction, and obtain permit if necessary.

13. If a male develops EDS over a period of time, or if a male that suffers from EDS finds relief from the condition, notify medical professionals immediately. If a female develops EDS, discuss this development with parents.

Standing or sitting 'in' a fly kill-zone may cause discomfort over an extended period. Seek help if you notice the following Symptoms:

Migraines, oscillopsia, lump in throat, color blindness, albinism, visual floaters, astymosism, thinning hair, hear heartbeat in ears, throat closes when lying flat, vomit in sleep, swollen face, low body temperature, low blood pressure, legs feel heavy, "strangling" feeling, "floating" sensation, thickening of finger joints.
If you have ALL of the above symptoms, please submit a video of yourself to Youtube.


It actually doesn't have to have a penny in it...the way it works has something to do with the flies eyes...the water messes with their eyes and they don't go near the door. It works, my Daddy has one at each of his doors and I asked the same of him...
