Our class continued to explore what changes we can make to marshmallows. We submerged the marshmallows in vinegar. We tore the marshmallows into pieces. Finally, Ms. Ward set a marshmallow on fire (do NOT try this at home). We found that all these changes were irreversible (could not be undone), but lighting the marshmallow on fire changed it the most!
Check out this video to learn the interesting history of roasting marshmallows (an idea that was created over 125 years ago!).
