President Obama attended the fifth annual White House Science Fair, which he explained is "the most fun event of the year." Taking time to experience each of the offerings and interact with the young science and technology students who introduced them he noted with mock caution that: "The robots I see keep getting smarter every year."

Among the school-aged exhibitors was 17-year-old Anvita Gupta, who was showcasing new software that looks for potential new drugs to treat cancer, ebola and other diseases. The US President also took the opportunity to dive into wave tank, splashing water about whilst learning how the lakeside power-generator design functions. 

The stars of the day were a group of elementary school girls who designed a battery operated device that can turn the pages of a book, in order to assist disabled readers. The group of girls were decked out in their girl scout uniforms with additional red superhero capes on top. Obama was impressed by the 6-year-olds' technical jargon, and by their casual use of words like 'prototype' and 'brainstorming.'

The fair was also an opportunity for the Obama administration to publicly demonstrate its commitment to backing science, technology, engineering and maths education, known as STEM. Obama made this point by saying to the innovating young thinkers: "It's not enough for our country just to be proud of you. We've also got to support you."
