Elon Musk tweets on Monday a video of a 'kid-sized submarine,' which he is testing for the rescue of the Thai children. Palisades Charter High School in Los Angeles is lending its pool and facilities for Musk to test this new technology.
"With some mods, this could also work as an escape pod in space," tweeted Musk.

As of Friday, Elon Musk sent members of SpaceX and Boring Company, his space and construction companies, to help with the rescue on the ground.
This technology is being developed as 4 boys were rescued with the hopes to see the others safe soon.
