Ms Li's class is getting ready for the Science Fair and Chad, Jordan, Zoe, and Keisha want to come up with a mind-blowing project. With the help of Chad's eccentric Auntie Kym, they decide to try and make a Black Hole! But class bully Shaun Simpson, seems determined to ruin it. No matter how they present the group project, using vacuum cleaners, clocks, and paint guns, Shaun always finds a way to wreck it.
The four kids work hard, (when Zoe can manage to stay out of detention!) have lots of fun and learn loads about the universe on the way. Finally, the day of the Science Fair arrives. Will Shaun try to ruin the Black Hole project again? Do the kids have a chance of winning first prize? And why is Shaun suddenly acting like he doesn't care? What happens comes as a surprise to everybody!
