I travel to Russia very frequently; microwave ovens are legal and used to heat & reheat foodstuffs. When I queried some Russian business associates regarding any 'ban' of microwave ovens in Russia, I was scoffed at.

Regards microwaved water and plant health.

1. L Ron Hubbard proved conclusively in the 1950s that plants respond to thought.

2. Unless a microwave mysteriously changes the chemical makeup of water, H20 goes in, boils, and H2O comes out. If something else comes out, maybe somebody should try microwaving lead -- perhaps they will get gold!

1. L Ron Hubbard proved conclusively that he was a loon, nothing more.

2. Microwaves do have the ability to alter the chemical composition of water with contaminants, which all water contains. The question is if this actually happens in real life and does it create something that inhibits plant growth.

I was shocked when I saw this "water experiment." So I decided to do my own experiment. I had also read somewhere that pouring microwaved water on seeds would prevent them from germinating. Well, I'm into the 2nd week of this experiment and unfortunately, all seeds have germinated are growing very nicely. I'm actually kind of unhappy about this result because I was hoping I could blame microwave ovens on the incredible increase in cancer deaths over the last two decades.

I have actually conducted this experiment for my biology class. I used 15 cups for tap water and 15 cups for microwaved water, for a total of 30 cups. I used generic potting soil and pinto beans. At first it seemed like the microwaved water beans were growing at a much faster rate. Four of my microwaved water beans were at 2 inches within the 4th day while most of the contorl were under 1 inch. On the 7th day is when things changed. Many of my microwaved water plants seemed to stop growing, one wilted. This could have been human error, or a special exception that would deem it negligible. I'm still growing them till this day, which is the 10th day. Only 5 of 15 microwaved water beans are still alive while 9 of 15 control beans are alive. Today, it seems like the ones that are still alive have roughly experienced similiar growth.

I probably will conclude on my paper that there is no difference.

I do have a question though. Can plants grow from pure water like distilled water? If so, the mutation or change in the solution of tap water would be negligible because plants will only use h2o. Correct me if im wrong, please.

My class replicated this experiment and showed it to be false.

Does cooled microwaved water kill plants?

I don't know why the URL in my last post loops back to this page. I guess I only though I knew what I was doing.

If you what to see the experiment results you can go to http://www.eclecticscience.net - there is a link "Does cooled microwaved water kill plants?"

I'm doing the same project for Science Horizons. My Results are telling me that microwave water is making my plant grow faster. I'm doing the project twice to see if both results are the same and so far they both are.

For Jaci Jowdy-
What is you test subject size. There is quite a bit of variation in plant growth as you probably know, and the more subjects you have the better. We only did the experiment for 10 days because the school year was ending, but now we are starting a new experiment with aquariums (testing both plants and fish). I have not boiled the control water, although it is bottled water, so it has been treated. For more info on our new experiment drop by our site - comments are appreciated.

I'm interested to know how your experiment turns out.

what if i do this proj. what would be my main problem for this and would i change the title/name of the proj.?

Sorry I acedentaly pressed enter. But my results are: Bolied water-25in.with 3 flowers, microwave water-26in. with 4 flowers, tap water-20in.with 1 flower, and bottled water-17in. with no flowers. I would love to know what type of plant ur granddaughter used for my project.

Cute

I am going 2 try this for my science project right now. THis is where I am gettin my information. Very Intresting!!

I did my own experiment with flower seeds with plain tap water, boiled water, and microwaved water. All seeds germinated (although I was hoping the microwaved ones wouldn't). Water is water is water. It has been down through eons of time and will continue to be water. This little girl's experiment was absolutely bogus. We've got enought hoaxes going on today. We don't need someone to pull this kind of stunt.

im doing mt own project.

My son's science fair project was rooting 1 slip of a ficus plant in room temperature microwaved water and 1 slip of ficus plant in tap water from our well. After 30 days of observation, the plant in tap water from our well has sprouted roots. The plant slip in microwaved water has not formed roots at all. Both plants were placed in the same window each in identical glass containers. The microwaved water was boiled in a glass container and then cooled to room temperature.

Although I appalled your son’s efforts to replicate this experiment, there are way too many variables to draw a conclusion from one control and one experiment. As noted in an earlier post, my class used 24 control and 24 experiment plants - and we hope other classrooms or individuals expand on this.

Also, as noted in an earlier post, my class and I are currently running two aquariums, one with microwaved water and one with unmicrowaved water. Again, we are technically working with one control and one experiment, and so it is hoped other classrooms or individuals replicate our results (which are not in yet, but I can say that both aquariums have been up for 9 weeks and both are very healthy). Ours is a double-blind study, and so my students and I do not know which tank contains the microwaved water. As a side note, every time something goes a little wrong in a tank, many students claim that the offending tank contains the microwaved water. Trouble is, this goes back and forth between the two. The students expect the microwaved water to be the culprit if something goes wrong instead of one of a thousand other variables that affect aquariums. This is why we do double-blind studies whenever we can - to avoid self-fulfilling prophecy from affecting our results.

We hope our results join a body of results. By itself, our experiment only begs for replication - but on a teacher’s budget, this is the best I could do. We received a grant which covered some of the cost, but this one isn’t cheap. After equipment, including water chemistry testing kits, expect it to cost over $300 if you are running two 10 gallon aquariums as we are. It’s also a lot of work, including getting a third party (in this case, my wife) to microwave the water and label the jugs. However, the science I can teach to my students is hands-on and related to our course of study - what more could you ask for?

Again, your son deserves praise for his good work, but now others (or he) needs to replicate the experiment dozens, if not hundreds of times before a conclusion can be made. Science theory always rests on a body of evidence, and the evidence cannot be trivial. My classroom work has only contributed to that body of evidence as well - more needs to be done before we can draw solid conclusions.

I hope to add a section to my website which includes third party experiments. If you're interested in posting results when (and if)I do contact me.

Hi,
When I started UNI, I had limited space so I cooked all my food in a microwave. 6 months later I was diagnosed with an autoimmunity. I didn't take any drugs ro meds and during that time I didn't stress. I have reason to believe that the increase in autoimmune diseases (maybe cancer as well) we see is due to the fact that more and more food companies switch to easy microwaveable food.

Our brains tend to want to connect all the dots, so to speak, and sometimes see correlations where there are no real correlations. Our cavalier attitude toward polluting our environment has lead to an increase in health problems globally. The only way to be sure if your microwave oven caused the problem is have someone conduct a study, and even this is difficult because of the vast amount of variables involved. The bottom line is: How do we know which variable (or combination of variables) caused the problem? The cause of most autoimmune diseases is unknown - but they have plagued us long before microwaved ovens came on the scene.

why does this happen to the plant being watered by microwaved water?
