Billionaire tech entrepreneur Elon Musk shared photos and videos of a metallic pod that may help rescue a group of boys trapped in a cave in Thailand.
Footage shared on Musk’s Twitter account shows a group testing the device in a Los Angeles high school swimming pool.
Musk said in a tweet Sunday evening that the pod — or “kid-size submarine” — was en route to Thailand and would arrive in about 17 hours.
“Hopefully useful,” he said in one tweet. “If not, perhaps it will be in a future situation.”
