Fascinating but Useless

This has fascinated me for a good few decades.....

Take a Helium balloon, drop your rear seats and weight the balloon in the center of the load area so it floats about 6" from the ceiling.

Now drive

Turn left and the balloon will move to the left, right and it will move to the right

Accelerate and the balloon will go forward, brake and it will move backwards.

After all these years, this still fascinates me that the air in the cabin actually moves around as you turn, brake and accelerate.

Fascinating eh?

:laugh: never thought of that before

Sounds like the balloon was an ex-biker :whistle:

Its one thing understanding the law of physics but its another thing to see them in action.

Take the "Wall of Death", its pretty obvious what a motorbike riding round in a big barrel could do, but plenty of people find that fascinating (dont know why though)

Or dont you get that john?

I have seen one of those, very entertaining it was - well worth a few quid.
