Foam? Those we see on the surface of the fizzy soda, beer and body wash? Yes it was somewhat similar but ours was produced by a Foam Machine. We will first inflate the Water Pool, next fill it up with water and last but not least turn on the foam machine. Foam parties are sure to create memories that last a lifetime. Foam Parties are fun for ALL ages & abilities. There is no better way to beat the heat than being covered from head to toe in refreshing foam!
