Girl Scouts meet Barack Obama at White House Science Fair 2015

Five Girl Scouts from Tulsa, Oklahoma, wowed President Barack Obama with a page-turning robot built out of Legos for the disabled at the White House Science Fair on March 23.

Wearing Superman red capes over their Girl Scout uniforms, the 6-year-olds showed off a page-turning robot, made from Lego blocks and designed for use by disabled people.

As the president toured the three dozen exhibits, he splashed water in a wave tank to demonstrate how a lakeside power-generating system works, and got the lowdown on the science behind the show.

A couple of the projects featured robots, including one that catches and throws balls.

This was the fifth White House Science Fair, which Barack Obama said was the “most fun event of the year”.

The president took the opportunity to tout science, technology, engineering and math education, also known as STEM, and touted his administration’s STEM initiatives as well.
