Helium
first take paper and make your glider attach a balloon
air is heavier than balloon, air rises
balloon
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.
good question
You could use the balloon as a mold for something by making paper mache and using the shape of the balloon for that item. Let's say you want to make a bowl. I would blow up the balloon, shred paper, and mix the paper with wheat paste. I would then put the paper mache on half of the balloon and let it dry. After it is dry I would pop the balloon and what I have left is a bowl shape. Then, I would paint the bowl and decorate it. Now you have a bowl.
Put a straw in the end of it and blow into the balloon. That should make it fly straight although make sure you don't use helium and make sure there is as little of wind around as possible. From Matthew
To make a Paper Mache Dragon, you need a balloon, a whole lot of toilette paper tubes, and tape. Blow the balloon up to make the body and then tape the toilette paper tubes to the balloon to make the 4 legs tail and neck. Once every thing is taped caver the dragon with paper mache. To make paper mache: One part flour, two parts water.
The hot air inside the balloon expands, making the hot air balloon fly.
