I would have to say without a doubt your friend was pulling your leg...
Something like this would be the smoking gun of UFO videos... And there's no doubt there would be a long topic here on ATS if something like that
was ever shown...
as for the coke and dry ice... I do know you can make the lid jump if you set it on the bottle with dry ice in it... The dry ice melting creates an
expansion of gas and the lid, if set loosely on the top, will jump to allow the gas to release...
Assuming you can get a good volume of gas flowing, you could potentially get the lid to 'hover'...
It's kind of like taking a beach ball & place it on a fan pointing somewhat upward... The ball will sit there and hover without falling off... The
air ends up bubbling around the ball, both lifting it and causing it to stay in place...
