Latex balloons?

Question

so i have like, 150 latex balloons i need to blow up for thursday. if i blow them up today, will they stay inflated by thursday or should i wait until wednesday? please help, i'd much rather blow them up now if i can!

Answer 1

Get a balloon pump. It will make things much easier. If you blow them up too early, they will only go down again.

Answer 2

They might shrink down slightley, but I think that they should stay inflated.

Answer 3

If you're filling them up with helium, wait until the last possible time you can get it done on time. We filled up a bunch of balloons one morning for a party that night and set them up with all of the decorations. When we came back at the end of the day, about half of them were falling down. If you're just filling them up with air, they'll probably still deflate quite a bit by Thursday.
