Black Hole High

After an argument, Josie's intelligence transfers to Vaughn faster every minute, to the point where Josie is on the verge of collapse and Vaughn rebuilds a cold fusion reactor for his father. Meanwhile, Josie's clone returns the floating Qi ball to Victor.

Josie experiences sleep deprivation and it causes her to wig out, until she realizes Vaughn is the key to the problem.

Corrine's need to schedule every moment of her life upsets Marshall, who wants to be able to spend some random free time with her. Before they can talk about it, Corrine's Venus Flytrap turns into a human being - a girl named Diana who attracts the attention of all the boys at school.

While his friends are away during a long weekend, Lucas stays behind to spy on Victor's movements. Instead, he finds a tesseract device hidden in Professor Z's office. After activating it, the school begins to fold in on itself like a mathematical tesseract. Lucas discovers what happened to Professor Middleton and learns something about Vaughn.

Tyler organizes the school's fundraiser car-wash event, but he overhears a conversation about a new "gravity sensor", develops the ability to camouflage himself, and uses this to find out what the science club is up to.

The science club uses nanotechnology to follow Tyler. Thing go bad when one of them accidentally swallows a camera.

Lucas is upset about continuously losing at Hearts, so he rigs his his glasses and a deck of cards with invisible ink to win. To bad that the effect is permanent and he might just go blind.

Marshall's rocket disappears into black hole energy and returns in a completely different form; only Vaughn can unlock its secret. Also Lucas starts to think he might be wrong about Vaughn.

When Marshall writes a prediction column for the school paper, he neglects to proofread his work and "Someone will diet" turns into "Someone will die." Things get scary when Marshall's predictions start to come true.

Josie skips Z's science class; the topic is chirality (mirror opposites) - molecules with left handed and right handed forms. During the class experiment a kernel of black hole energy sizzles in the test tubes- suddenly Durst and Professor Z switch roles.

Vaughn discovers a security tape of the Pearadyne explosion showing Sarah leaving behind Victor and speaking to Corrine when she first fell into the wormhole, but refuses to believe that Corrine cannot recall what happened. When they end up stuck together, Josie and Marshall get second thoughts about the two.

When Lucas's gravity sensor is operational, meaning they can now see when the wormhole opens, Josie worries that Vaughn will enter the wormhole without anyone's consent in an effort to talk with his supposedly dead mother. Josie enters the wormhole by herself and is transported to October 4, 1879.

Vaughn is lost in the wormhole and travels back in time to April 11, 1977, so Josie goes into the wormhole again to rescue him. Meanwhile, the rest of the Science Club learn more about the nature of the wormhole and the major time periods it connects to in an effort to bring back their friends.
