flexible and stretchy
balloons have carbion dioxide (vaccum) so in the world today vaccum is the best insulaters
The air is too strong, which makes the balloon sink, along with the weight of the balloon's material.
Heating a balloon causes the air inside to expand, increasing its pressure. If the pressure exceeds the elastic limit of the balloon material, it will rupture and pop.
CEMENT
A gore on a hot air balloon is a section of lightweight fabric that makes one of the panels of the balloon. The gores are cut from flat material and stitched together to give the balloon its shape.

When a balloon pops, the elastic material of the balloon stretches beyond its limit, causing the balloon to burst open. The sudden release of air inside the balloon creates a loud popping sound and the balloon ends up in smaller pieces.
When a balloon is rubbed against a material (such as wool or hair), it acquires an electrostatic charge. This charge creates a force between the balloon and the ceiling, causing the balloon to stick. This force is due to static electricity.
Begin by placing a semi inflated balloon on the end of an empty soda plastic soda bottle. Then squeeze the bottle and watch the balloon inflate slightly, this demonstrates when the air is compressed inside the soda bottle it creates pressure to fill the balloon and push it up. This is not only a great way to show this property of air to somebody, its cheap for a small class experiment.
Adding water to a balloon changes the distribution of forces acting on it. The water inside the balloon adds weight, causing the balloon to stretch and become thinner. This makes the balloon more susceptible to popping as the tension in its material increases.
Magnesium and Titanium.
A balloon expands when air is blown into it, causing the rubber or latex material of the balloon to stretch and increase in volume. As more air is added, the pressure inside the balloon increases, causing it to expand and become larger in size.
