After freezing fruit with liquid nitrogen in Brian Klett’s physics class, Cristina McBride (11) learns about its cold effect by using a hammer to smash the pieces.  “The fruit smashed instantly because the hammer was hard itself, ” McBride said. “When you touch [the fruit] too much, it gives that weird tingly feeling, but when you smash it, it feels satisfying.”
