A balloon is a bag made out of rubber, you can fill with in any kind of gas, for example: helium, oxygen or air. The rubber balloon was invented by Michael Faraday in 1824. The same year as the balloons, the electromagnet was invented. Helium balloons last less than air balloons because the enclosed helium atoms escape through small holes.
Party balloons are mostly made of rubber trees, they are the most popular kind. Another kind is the hot air balloon. It is the first successful flight technology that was invented by human. The first modern hot air balloon was made in the UK.
Water balloons are made to be easily broken. They are very popular in celebrating the Holi and Carnival in India, Nepal and other countries. The Yo-Yo balloon (Yo-yo Tauris) is a game that is played with water balloon, the players "fish" for the balloons with a hook at the end of a twisted paper string.
