holiday inflatable - giant floating (indoor) balloon Answered

 We have a Gemmy inflatable at work (a giant Homer Simpson -- about 8 feet tall) and we were wondering if we could somehow fill it with helium and float it on the ceiling.

We're concerned that it's too permeable (when the fan is not going, it deflates FAST).  One idea was to coat the inside with polyurethane (turning the fan on to blow it throughout the balloon) but that seems like it wouldn't work very well (too patchy), and could make it too heavy.

Another option would be to take a bunch of balloons, insert them into the Homer, and then inflate the smaller balloons (and tie them off).

Any other thoughts or suggestions?

Your best bet is probably to go with several balloons that are designed to hold helium for several hours (or more). It's thin stuff and hard to contain with lightweight materials.

Yes - a whole bunch of Mylar "happy birthday" balloons.  We have one still floating over two months after purchase.

Yes, that's the stuff. I heard tell of a wedding reception in which the (non-Mylar®) balloons were done the day before - not up the day after...
Apparently Mylar® is PET.
