Student science experiment finds plants won’t grow near Wi-Fi router

Mother Nature Network – by Jenn Savedge

Five ninth-grade young women from Denmark recently created a science experiment that is causing a stir in the scientific community.

It started with an observation and a question. The girls noticed that if they slept with their mobile phones near their heads at night, they often had difficulty concentrating at school the next day. They wanted to test the effect of a cellphone’s radiation on humans, but their school, Hjallerup School in Denmark, did not have the equipment to handle such an experiment. So the girls designed an experiment that would test the effect of cellphone radiation on a plant instead.  

The students placed six trays filled with Lepidium sativum, a type of garden cress into a room without radiation, and six trays of the seeds into another room next to two routers that according to the girls calculations, emitted about the same type of radiation as an ordinary cellphone.

Over the next 12 days, the girls observed, measured, weighed and photographed their results. Although by the end of the experiment the results were blatantly obvious — the cress seeds placed near the router had not grown. Many of them were completely dead. While the cress seeds planted in the other room, away from the routers, thrived.

The experiment earned the girls (pictured below) top honors in a regional science competition and the interest of scientists around the world.

According to Kim Horsevad, a teacher at Hjallerup Skole in Denmark were the cress experiment took place, a neuroscience professor at the Karolinska Institute in Sweden, is interested in repeating the experiment in controlled professional scientific environments.

I’m sure the world will continue watching these young women, and this experiment, for many years to come.

  1. Considering that there are over 200,000 cell phone towers and antenna in the USA, what does that mean for the people living in this gaint electronic frying pan?

  2. Greg, How about the Blu tooth one clips to their ear. Wouldn’t RF effect the brain same as a cell phone held up to the ear? My router is in the office I may have to place a small plant close to it to see happens.

  3. To readers of this, how about duplicating the experiment several times?
    I would do it but I don’t have that stuff available at home.

  4. Very interesting results which just go to prove that the effect of microwave transmitters in phones and wi -fi routers DO pose a risk to health. I mean this is a pretty undeniable result wouldn’t you say? Reminds me of the school girl that boiled water in a kettle and also in a microwave and then allowed it to cool down over night. Then she watered the plants, the plant that was watered with boiled water thrived whilst the micro-waved water plant shrivelled and died…Hhhhmmmmm!. Again pretty obvious really, not a good thing to put in your body no matter what anyone says about microwaves being harmless, “all they do is vibrate the molecules” … is that so!!!

  5. I have houseplants in my office where all my electronic equipment is kept – computers, router, cell phone charger, etc. They do as well as the plants in the other rooms, even though they also get somewhat less natural light. I would like to see further controlled studies like this, making sure to eliminate other possible variables.
