Checking out other news sites about the Democractic convention and came across this funny bit on the BBC site:
When I think of party conventions, I think of balloons – why?
The “balloon drop” has long been a staple of the convention finale.
In 2004, the Republicans dropped some 100,000 bio-degradable balloons on to the heads of exultant conventioneers.
Why is this done? Because everybody likes balloons. Especially when lots of them are dropped from the ceiling at the same time.
