It is fun seeing kites and balloons float in the sky. With time, we even learn how the laws of physics make it possible for balloons to float. Regardless, a fantastic event, which occurred in Croatia, will leave you stunned. 4-time Guinness world record holder, Ivan Trifonov, was at the seat of the daring adventure. It was another great feat for him. #Croatia #NatureParkVelebit #IvanTrifonoc #Adevnture #MametCave #GuinessRecordHolder #HotAirBalloon #AmazingFeat
