This is a small submarine designed by Elon Musk to save children who are trapped in Thailand

The divers in Thailand have successfully rescued 4 of the 12 boys trapped in the cave flooded and hope to save the remaining children in the next few days.In the meantime, Elon Musk has built a special diving device, when conventional diving equipment cannot be used.

On Saturday, Musk began to have the idea of ​​building a "small submarine for children, using liquid oxygen gas pipes as shells of Falcon missiles".Elon asked SpaceX's engineers to start assembling and said that by the end of the 7th day it would be ready to use.

By the time the equipment was completed, Thai authorities had also begun to rescue the remaining boys, so perhaps Elon's device would not be used.But Musk said on Twitter that 'although not useful here, it will probably be used in the future'.

The ship was built from the shell of the Falcon rocket

On Sunday, Elon posted pictures of the finished product.'After 3 hours of testing in LA, he has now flown to Thailand,' Musk said on Twitter.He also posted a video of this submarine experiment in the pool.This submarine's pipeline is very small, at its narrowest point only about 38cm wide.
