Tech Team and the Poison Plates

Many of the local school's pupils are falling ill after lunch ... and it's not because of questionable canteen food. It's poison! But there are only two groups affected: the super-cool girls and the comic book fans. Who would hold a grudge against such opposite cliques, and why would they want to poison them? When there's a school mystery that needs solving, the S.M.A.R.T.S. are ready to put their sharp minds to the test! It will take their best critical-thinking skills and scientific reasoning to get to the bottom of this lunchtime puzzle.
