History of balloons
History of Toy Balloon - Who Invented the Rubber Balloon? Toy balloon is a small balloon made of rubber or aluminized plastic and inflated with gas, usually air or helium. It is mostly used for child play, party decoration, and in advertising. Their sizes typically vary from 10 to 30 centimeters in diameter but can be made in any size or shape. Toy balloons can look like a relatively modern invention, but their variations existed for centuries. There are illustrations from the 14th century that depict balloons made from inflated pig bladder. Galileo also used an inflated pig's bladder in an experiment in which he tried to measure the weight of air. Michael Faraday invented the first rubber balloon in 1824. He used them in experiments with hydrogen at the Royal Institution in London. He made a rubber balloon out of two sheets of rubber which he covered with flour on the inside so they would not stick to each other but leave edges uncovered and pressing them together. Rubber
