Have 12 trays of 400 cress seeds. In two rooms, place six trays each. One of the rooms should be exposed to Wi-Fi (mobile) radiation. The rooms should be of the same temperature. Water given to the plants should be of the same amount and exposure to the sun should be the same for a period of 12 days.

This brilliant biology test has attracted even international attention from known radiation experts and biologists. The girls who did the experiment are from Hjallerup School, North Jutland. Their experiment was based on the fact that it was difficult to concentrate during school days when they slept with their phones next to their heads. They also found it difficult sometimes to sleep when they did the same.
The school was not fully equipped for an experiment to test what effect radiations from mobile phones had on them and so the girls looked for an alternative solution in Cress.

They had six trays of the cress seeds placed in a radiation free room and another six trays near two (Wi-Fi) routers in another room. Radiation from the routers is the same as that emitted by normal mobile phones.
They waited for 12 days while observing, monitoring, weighing, measuring and taking pictures. The results were clear: the cress seeds that were next to the router failed to grow while some were either dead or mutated.
The successful experiment won the girls finals in the “Young Scientists” competition. It was just the beginning however, because renowned scientists from Holland, England and Sweden got interested in the project. One of the professors, Olle Johanson, from Karolinska Institute, Stockholm, will redo this experiment with a Belgian colleague. He was impressed!

“The girls stayed within the scope of their knowledge, skillfully implemented and developed a very elegant experiment. The wealth of detail and accuracy is exemplary, choosing cress was very intelligent, and I could go on,” he said. “I sincerely hope that they spend their future professional life in researching, because I definitely think they have a natural aptitude for it. Personally, I would love to see these people in my team!”
The girls, still surprised by the attention their experiment got, have not decided on future careers yet. They however, won’t be sleeping with a mobile phone next to their bed anymore.
