In the episode HELL OR HIGH WATER on Prison Break, how did the inmates that escape from Sona breathe under the water and make it through the sea?
I mean what is that device they used under the water?
They used miniature SCUBA gear, specifically, hand refillable oxygen bottles.
Most snorkels will allow you to swim underwater for around two minutes before you have to surface to gasp for air.
But a new snorkel-style gadget means swimmers can take even longer to explore the deep.
The Scorkl holds enough air to let you breathe underwater for up to 10 minutes, and can be reused time and time again, simply by being pumped up.
I don't have a screen capture from the TV series but devices look incredibly similar to these...
