Science Fair

Alex steht, was Naturwissenschaften betrifft, stets im Schatten ihrer Schwester Annie. Als Annie in die Schlußrunde eines vom Chemiewerk veranstalteten Wettbewerbs kommt, will Alex nicht mit dabei sein.

Annie's science project has been chosen as a finalist for the big science fair to be held at the Paradise Valley Chemical Plant. The whole Mack family is looking forward to spending Saturday at the science fair rooting Annie on, except Alex. Not only is she sick of witnessing Annie's triumphs, but the chemical plant is the worst place for her to be. It's crawling with plant spies who are constantly on the look out for ""the kid.""
