Pocket Lab

Pocket Lab turns any phone into a science lab. Many kids don’t have access to labs or equipment at school. With Pocket Lab, a student films an everyday experiment, like a key swinging on a string, and the app measures real physics from the video. All they need is a phone and something from around the house. Meta’s SAM 3.1, through the Meta Model API, tracks the object through every frame of the video. Our code turns that path into measurements, using the object’s own size as the ruler and the real frame rate as the stopwatch. In our test, a key on a string swung for 1.29 seconds and the app measured gravity at 10.28 meters per second squared, within 4.8 percent of the real value. Kids predict first, then earn medals, XP and collectible cards, take a science quiz, and play a gravity arcade game on the Moon, Mars, Earth and Jupiter.
