If you are performing at a party, you can use one of their ordinary round party balloons.

 

 

Claude Chandler introduced the Card In Balloon concept.

 

The first balloon was invented by Bartolomeu de Gusmao, a priest who was demonstrating his idea for an airship by launching a miniature model that used a dried animal bladder to hold the air. The rubber balloon was invented by the famous scientist Michael Faraday as a vessel to hold hydrogen. Latex balloons as we know them today were first manufactured in 1847 in London.
