Titan sub: Coke can shows how 'implosion' may have happened

A video of a Coca-Cola being instantly crushed by water pressure gives an idea of what likely happened to the destroyed Titan submersible that claimed five lives. The pressure chamber on board OceanGate's 22-ft vessel suffered a'catastrophic implosion', authorities revealed on Thursday, and the men aboard tragically perished. The implosion would have been caused by a sudden change from low to high pressure inside the sub, possibly triggered by a defect in the sub's walls. Experts say the crew and passengers would have been crushed within a fraction of a millisecond, an event so fast it would have been over before they realized what was happening and so violent it's unlikely to leave anything but a mist of human remains. A video posted by James Hambley, a YouTuber who goes by the alias Barded Science Guy, shows a similar implosion happening to a Coke can.
