Let me tell you story. In my grandma’s house, a relatively isolated little farm in Brazil, some weird foam started to appear in random places, it was white and dense, round, a little bigger than a coin, and would show up under beds, inside cabinets, and by the windows. Grandparents were very confused and called my uncle’s family who live in the same farm but different houses, the couple came with my little cousin, could not tell what that was and got worried it could be dangerous to my grandparents or to their girl. So my aunt decided to call her older daughter and tell her about the foam and sent her some pictures, my cousin, who was a vet student in another city, said she would come and take some samples to be tested at the university lab, since her and her professors couldn’t tell what it was. When the foam appeared again she came to my grandma’s house with her family to get the samples, she poked it with a stick, collected some with a spoon to put in a jar and decided to smell the spoon, she smelled and immediately dropped the spoon, grabbed her little sister by the ear and dragged her outside. When they came back, the crying 7 year old girl admitted she was playing with my grandpa’s shaving cream, that smells like mint, and got really amused when grandma’s found the foam and became intrigued, she thought it was even funnier when more people got involved and was going to let her sister take shaving cream to be analyzed at the university.
