Monday was the 2015 White House Science Fair, and more than 100 students got to show off their projects, including a Girl Scouts troop from Tulsa who built a battery-powered page turner. The project was made from motorized Lego toys for people with disabilities that make it difficult to turn pages while reading.

The girls, all 6 years old, are members of the "Supergirls" Junior FIRST Lego League Team from troop 411, and wore capes to the White House. Adorable!

There was also a dog there named Derby who had 3D-printed legs.
