In the ‘El Hormiguero’ program we continue looking for the best experiments. On this occasion, Marron has brought a simple experiment that anyone can do at home and that will surprise us. To do this, we are going to make an amazing effect with a balloon, threads and white glue.
To do this, we have surrounded a balloon with threads, and we have glued them with white glue. Once the glue has set, the threads have remained rigid and adhered to the rubber, so that when we puncture the balloon, the regions where there is adhered thread present greater resistance to contraction than those where it is not. This means that in the end, we have an abstract form as a result.
Elasticity
The balloon is made of an elastic material, which can deform proportionally to the force applied to it, just like a spring. In this way, as we increase the amount of air inside the balloon, the pressure inside the balloon increases, making a greater force on the surface of the balloon and thus causing it to expand.
How much it inflates ends up being a balance between the elastic force of the balloon and the pressure of the gas.
