Back to the balloons

Ok, so had a little idea of hanging the balloons and seeing if they work instead of floating. With the time straits i couldn't really wait, so i could only get 'england' balloons at the last minute. Unsure what to think with the outcome at the moment. I know that i need a lot more balloons, i think when i need to do it i either need to have no background showing or i need a 'balloon sculpture' that will allow the film to be projected on.

Apologies for picture, lost all my sd cards & my camera which is wonderful news!!
