Helium is so expensive these days... have to try this
Helium - Alternative education site
Balloons, Helium alternative and Helium balloons on Pinterest
Great party idea
A perfect alternative to the budget that doesnt included helium balloons. These quick and easy balloon arrangements require nothing more than some oasis, a vase, balloons and balloon sticks. I have added some tissue paper to fill in around the base. These balloon arrangements can be altered to suit any theme.
