This is a beautiful model of a readymade Hot Air Balloon. This Hot Air Balloon is made of strong kite paper. You can see there is a frame – a ring of thin wire. There are cross-wires attached to the frame and in the middle is the WAX PAPER – this is the fuel which will power the Hot Air Balloon. 
Light the wax paper with two people holding the balloon. As the fuel burns the air inside the balloon will become hot. As hot air is lighter than cold air the balloon will soon take off. The balloon will travel several hundred meters up in the air until it runs out of fuel. Then by gravity it will slowly descend down. This work was supported by IUCAA and Tata Trust.
