This is an air balloon model. It was designed to serve as a addon to a present.

The ballon itself has a height of about 10cm. Originally, it was intended to glue the heater and the basket together and apply this to the balloon via strings (thats the inner bridge inside the balloon is for). But it turned out that was in fact easier to directly glue the basket/heater combo to the ballon.

The model was finalized with fine abrasic paper and acrylic paint.
