We’re about halfway through this year’s Hack Day…

The brief: create a digital product that helps people learn. We split up into five teams and got cracking with our top secret plans. Tomorrow at 2 we pitch to our three supercalifragilistic judges: Dave Patten, head of new media at the Science Museum; author and publisher John Mitchinson; and tech journalist/academic Aleks Krotoski.

What will they make of our creations? You’ll have to tune in tomorrow…
