Plants and Wi-Fi routers
Someone here may be interested in: Plants won't grow near Wi-Fi routers, experiment finds
Some girls in Denmark got some sort of an award for their experiment. Students elsewhere should find i easy to replicate the experiment and confirm or refute their results.
In summary: The girls placed six trays of Lepidium sativum seeds (a garden cress grown commercially throughout Europe) in a room without radiation, and an equal amount in a room next to two Wi-Fi routers. Over a 12-day period, they observed, measured, weighed and photographed the results. Even before the 12th day arrived, however, the end results were obvious: The cress seeds placed near the routers either hadn't grown or were completely dead, while the seeds placed in the radiation-free room had blossomed into healthy plants.
