(CBS) — Two Chicago area students were honored at the annual White House Science Fair Monday.

14-year-old Trisha Prabhu of Naperville developed a program called “re-think” that’s aimed at combating cyber bullying.

She says it helps adolescents think before posting online.

“If I were to go on a social media site and post something like, “You are so ugly,” rethink is able to detect first of all that that is offensive and then it alerts adolescents.”

And 11-year-old Lily Born of Skokie showcased the Kangaroo Cup.

She invented it after seeing how hard it was for her grandfather who suffers from Parkinson’s disease to hold a cup.

Born says her advice for young girls who want to invent, is to just go for it.

Both girls were being honored among dozens of students from across the country who had won various science, technology, engineering and math competitions.
