It is not foam. According to the CDF Aviation wikipedia page:
"The retardant used to slow or retard the spread of a fire is a slurry mix consisting of a chemical salt compound, water, clay or a gum-thickening agent, and a coloring agent."
Many years ago the mix contained "borates" that had a tendency to be worse than simply letting the fire burn.
Under "Aerial firefighting": "Borate salts were used in the past to fight wildfires but were found to sterilize the soil, were toxic to animals, and are now prohibited. Newer retardants use ammonium sulfate or ammonium polyphosphate with attapulgite clay thickener or diammonium phosphate with a guar gum derivative thickener." [footnotes omitted]
Foam
Foam rubber it is made up with a foaming agent for creating an air-filledmatrix structure. Those foam rubbers are normally either polyurethane foam or natural foam rubber latex.Foam rubber can also created from chemicals polyol,Latex foam rubber.Used in:mattressesInsulationFurniturePackagingCostumes
It is SiO2 (Silicon dioxide), Salt water and foam made from ducks
in 1380 by Richard thinkton, England, Dublin.
It starts with a plastic known as styrene. Liquid or soft styrene has air or gasses forced through it, causing it to expand or foam up. Styrene+ foam= styrofoam. The material gets lighter as it foams up, and later solidifies.

By securing it in foam, and then in a crate or box made of a hard substance. Or use lots and lots of bubble wrap. It's what one of my cousins used for his egg drop experiment
