Curse the man who invented helium! Curse Pierre Jules César Janssen!
This Big Butt Skinner weather balloon pin is perfect for the prankster with the heart of a hardened criminal or that of a ten-year-old boy. Either way, it’ll make you shout, “hurrah for science!” Each 1.5″ soft enamel pin comes on a custom-designed backing card and is secured with a rubber clutch so it won’t blow away. Remember, whoever brings down this balloon doesn’t have to learn fractions!
