The science behind your soapy water… 

A bubble is made of a very thin sheet of soapy water called a soap film. Soap molecules line up on the inside surface and the outside surface, and trap water molecules in-between – like a molecular sandwich. 

The reason soap molecules do this is that they have one end that is attracted to water molecules and another that is repelled (pushed away) from them. The water slowly evaporates and eventually the soap film will break. 

Adding glycerine to the mix makes longer-lasting bubbles because glycerine holds onto water, so it takes longer for the water to evaporate.
