Weather machine (death ray or barometer)

I am getting a suspicious feeling about the spinning machine outside Mr. Matus's class room Mr. Matus SAYS that it tells me the wind speed but I know better. I know that it's a weather ray that will make it never snow anywhere ever. That little devise inside his room just shows predictions from the weather channel. We are going to ask Mr. Matus about it  LATER... OK all he said was "you'll see oh you'll see."

On the reality side the new weather vane is working great. It is giving accurate information

(see this)

because of a walk outside I hypothesized that it was 75 degrees when we looked at the weather statistics  it was 73.2

That seems to prove it
