You're really not convincing anyone with insults. I agree that this experiment would have been better if the premise was more explicitly whether living right next to a WiFi router inhibits plant growth. I am not sure they came out and said that. There are a few obvious things to try before you come to the conclusion that it does. If you do come to that conclusion, you do not jump to the conclusion that it is harmful to humans. Even the children in the video could figure that out.
