Well done Mr Frog, however, whilst not wishing to rain on your parade, the wind at the time didn’t really seem strong enough to turn the arrow completely around AND given the angle of the arrow I reckon you cheated and shot it from the ground & not the roof, but still a good shot none the less!!!
Not so sure about the golf ball in the boat though as I’m sure you must have been using some sort of radio controlled trick ball as it went from yellow to white & then back to yellow.
Just my thoughts on the matter.
Quality video production none the less, looks like you are now setting a standard that we will all need to strive towards.
As for a “blowing” friend, I believe a bike pump does just as good a job without you needing to get lips too close to the orifice!!!
