President Obama spent some quality time with a group of six-year-old Girl Scouts from Tulsa, Oklahoma on Monday as part of the 2015 White House Science Fair.

The Girl Scouts—also known by the nickname “Supergirls”—attended the science fair after designing a battery-powered page turner meant to help people who are paralyzed or suffer from movement-related diseases like arthritis. They used Legos as the building blocks for the development of their prototype.

The White House Science Fair features projects from innovative students around the United States. This year’s fair is focusing on girls and women who are doing extraordinary things in science, technology, engineering, and math (STEM).
