Writer John Sullivan has sold his family adventure spec Science Fair to Disney for $275,000 against $575,000 according to The Hollywood Reporter.

With echoes of Night at the Museum, the screenplay centers on a science fair where all of the kids' projects -- think papier-mache volcanos and fungus -- come to life.

"I grew up on stuff like Explorers and The Goonies and Weird Science, " said Sullivan, whose mother teaches sixth grade. "I really wanted to explore something that was more family-friendly and something that I would actually like to go see myself if I was 12-16. There's a lot of wish fulfillment in that. Movies like this are just fun to write."
