This ball has made a big splash on the anniversary of my daughter, 5 years. Needless to invest in a bomb Helium, relatively expensive. I easily inflated with a big straw in less than a minute at the mouth. After inflation, just remove the straw. It does not deflate, even after a month of use because there is a safety valve where it is inflated. As it is very light, I stuck with the head on the ceiling and he held very well.
