How long will a 3ft balloon explosion stay afloat for?

How long will a 3ft balloon filled with air and lots of small balloons stay afloat for please?

ANSWER:

Hi there,

Only balloons filled with helium float. Air filled balloons do not float.

The kind of exploding balloon you have in mind, also called a "balloon bomb," is normally suspended from the ceiling.
