they have to do another experiment to know if that was the cause instead of the wifi.
Then don't publish knowingly incomplete and/or shoddy results. We can wait. :)
Most universities have a anechoic chamber that could do this experiment very well. But, that's beyond a middle school or high school.
I have to wonder about the reaction here.
If this video was just about kids doing cool stuff, that would be awesome. Don't get me wrong - I love experiments. I love when smart kids apply their brains and test stuff. This is awesome, we need more of this. I've, personally, donated significant amounts of time and money to kids in my community to learn about engineering and science.
But, as evidenced by the end of the video - this video wasn't about showing off cool science done by smart kids. It was an attempt to to use some shoddy experiment to fear monger about RF.
I won't be making personal decisions based on a kid's school experiment. And, I see too many adults who lack critical thinking and who have very little understanding of radiation, magnetism, etc.
This isn't about the kids. This is about the fear mongering from the adults.
I just don't see them pushing conclusion here. I see the opposite, pushing science itself and a reminder that the results are sometimes not what you would expect.
Curiosity would lead them to consider the WiFi preventing all growth absurd, and look for the real cause. That would be a valuable and interesting experiment. It's when it gets infected with predetermined conclusions that it's just pretend experimentation.
I saw that they used an LED bulb and wondered how much RF those give off. Surprisingly my RF meter showed basically nothing on three different brands of LED bulbs. It would have been comical if their light source gave off more than the WiFi unit.
They appear to have measured RF in both setups.
