64" Gigaloon Numbers

Gigaloons are huge.  54" tall when inflated (64" uninflated).  2 inflation points.  Numbers 0-3, 5, & 7-9 will float by filling the upper portion with helium and the lower portion with air (both sections of numbers 4 & 6 must be filled with helium to float).  Or, fill both sections with air and use the tabs to attach them to a line.
