This edible chickpea foam, or aquafaba, as it is commonly known, is made from the water chickpeas are cooked in. You can use it as a substitute for egg in baking or even better as fun, non-toxic play foam for kids! Plus, it’s science, too!

The Science of Chickpea Foam

Foams are made by trapping gas bubbles inside a liquid or a solid. Shaving cream and dish washing suds are examples of foam, which are mostly gas and a little bit of liquid. A smoothie, whipped cream and meringue made from whipped egg whites are examples of food foams.

Aquafaba, or chickpea water, is the liquid leftover from cooking chickpeas, and it makes a great foam. Like other legumes or beans, chickpeas contain proteins and saponins.

The combined presence of these substances in chickpea liquid means that it will produce a foam when agitated and air is added to the mixture.

The cream of tartar is a stabilizing ingredient that helps create the foam faster and makes it firmer.

Play Ideas for Edible Foam

This sensory foam is perfect for an afternoon of play! To minimize the mess, lay a shower curtain or tablecloth under the container.

If it’s a nice day, take it outside; it won’t matter if you get foam everywhere.

Here are a few simple play ideas…

  • Set up a treasure hunt with plastic or acrylic jewels.
  • Add a favorite theme with plastic figures.
  • Add foam letters or numbers for an early learning activity.
  • Make an ocean theme.

When you are done with your foam, wash it down the drain!
