She was invited to "Strahan, Sara and Keke" to show off her "Kids Fun Portable Sink."
McGuire won an invention contest at her South Side school with a design for a portable sink. She said there was one time she was at the beach and wanted to eat some potato chips, but ran into a problem.
"I had just finished playing in the sand but there was nowhere to wash my hands nearby," she said. "Then I thought, what if I had a sink I could carry with me to wash my hands and eat the snacks?"

They created the sink so they'd have a way to keep their hands clean on-the-go.
McGuire showed Michael Strahan how to use it.
She and other "kidventors" featured on Friday's show also got a nice surprise.
Entrepreneur and investor Kim Perrell presented each of them with checks for $5,000.
