Dip Your Frog to Keep Your Milk Fresh

Russia Finland dipped frogs in milk to keep it from spoiling
Has anyone ever asked you if you have a frog in your throat? If you lived in Russia or Finland  you might literally have had that affliction, simply from drinking a cup of milk. 

In the days before modern refrigeration, inhabitants of Russia and Finland kept milk fresh by dipping a frog in it. 

The practice may seem bizarre, but it is well rooted in science. Russian brown frogs emit peptides that combat the growth of salmonella and other dangerous bacteria. 

An Extra Leap for Magnetic Personalities

frogs levitate in a strong-enough magnetic field

Mark Twain (who is featured in multiple posts here on Commonplace Fun Facts)¬†wrote about the lengths some people will go to in order to get a frog to outjump other frogs. One trick that wasn’t discussed in The Celebrated Jumping Frog of Calaveras County was magnetism.

If only he had known that if you put a frog in a strong-enough magnetic field, it will levitate.
