...Balloons last longer?

Question

How can I make balloons last longer?

I need some balloons for friday afternoon when I come back from San Diego but the thing is i leave on wednesday...

I heard of something that u can put on them to make them last longer i think its some kind of foam but im not sure.

Has anyone used this?

If so can i have the name of it please...

Or is there somthing else i can use?

Thanks in advance.

Answer 1

The stuff you are looking for is called "High (or Hi) Float" I doubt even with Hi-Float the balloons will stay up that long. Mylar balloons would last longer.  

Answer 2

the metalic balloons last longer than reg balloons
