Floating balloons? Do you mean if it is filled with helium, will it fly? Children nowadays like this kind of balloon very much. If you want to buy helium balloons for children, you'd better recognize them clearly, because many vendors pretend to be helium balloons, and the cost of hydrogen balloons is relatively low. So I suggest you go to a regular place to buy it, with trademark registration and gas insurance; Helium sellers will be more reliable if they have this guarantee. I bought helium balloons to decorate the wedding venue before, and bought them at Tmall Anyifei flagship store. I hope I can help you.
