watch the 15 second video on Twitter:
https://twitter.com/MayorofLondon/status/1365322929601449991?s=20&t=QM_astREhO3kb-xzoXvHMA
it is COMPLETELY FAKE ON EVERY LEVEL.
here is how real hot air balloons are filled - the balloon is first filled using a special high power fan designed specifically for filling hot air balloons:
then when hot air is added it is never allowed to come within FEET of the actual balloon material because it would instantly melt the balloon on contact.
no measures to keep plastic bag away from direct heat are taken in the video posted by Mayor of London because the video is completely fake.
i did the math ( tell me if you care to see it ). that Passat Wagon would have produced about 500 liters of exhaust idling for one minute. you would be able to fit three 500 liter balloons inside the passat itself - one in the front seats, one in the rear seats and one in the trunk.
the fake video over-states the volume of exhaust by a factor of 20X.
or about as much as the safety and effectiveness of Covid Vaccines was over-stated.
if cars really produced as much exhaust as the video claims underground car tunnels would get completely filled with exhaust in 5 minutes, all the engines would stall and when people got out of their stalled vehicles they would suffocate instantly …
tunnels have ventilation of course, but it is only able to keep up with the volume of exhaust because the actual volume of exhaust is only 5% as much as shown in the fake video …
oh and by the way my last THREE cars all automatically shut the engine off when stopped so this isn’t personal to me in any way.
i just don’t like having my intelligence insulted.
