15-year-old high school student, Angelo Casimiro submitted some pretty cool shoes to this year's edition of Google Science Fair, "a global online science and technology competition open to individuals and teams from ages 13 to 18."
What do the shoes do? They charge your phone when you step. So if you are out and about and your phone needs some juice, you can just strap your phone (or any other rechargeable battery device) and your steps will charge your phone.
Pretty cool if you ask me!
