They can be inflated with normal air through a straw which you insert into the valve, in which case it does not float away.
They can also be inflated with helium, in which case they float to the ceiling, so they should be tethered to a weight. They last for a few hours.
Tip: Do not overinflate the balloon, it can pop!
