Babloons: In the USA, flying balls of foam were invented
The American company SmileCloudsUSA has come up with an eco-friendly alternative to balloons - babloons (bubloons, from English words bubble - foam and baloon - balloon). The mixture of foam with helium is generated by a special machine and rises to the surface, passing through the figured slot. After that, a "cloud" thickness of several centimeters is cut off, and it flies into the sky. Forms can be any - from hearts and cats to letters or numbers; The advantage of babluns over traditional balls is that they decompose completely in the atmosphere and do not harm the health of birds or animals - they sometimes eat deflated balls.
Machines for creating babloons take up a lot of space, and their purchase or rental is currently available only in the USA, but you can enjoy videos on YouTube or in the instagram of the company.
