You can make a hot air balloon in your home. For this you will need an electric toaster and a thin walled plastic bag 30-cm wide and 60-cm long. Fix two vertical wires on the toaster to hold the plastic bag. When you switch the toaster ON then the coil inside will start glowing and draughts of hot air will go up. Now place a thin walled garbage bag on these wires. Switch on the toaster. After some time you will see hot air filling the bag. Slowly as the bag fills with hot air it will become round and after a while you might have to hold the ends of the bag with your hands otherwise the bag might just take off. On leaving the bag it takes-off like a hot air balloon. See and enjoy this action once again. This experiment of the hot air bag can be easily demonstrated in a classroom.
