2023 Titan submersible incident 

On 18 June 2023, Titan, a submersible operated by OceanGate, disappeared in international waters in the North Atlantic Ocean, approximately 400 nautical miles (740 km) off the coast of Newfoundland, Canada. The submersible, carrying five people, which includes Stockton Rush (CEO of OceanGate), Shahzada Dawood, Suleman Dawood, Hamish Harding, and Paul-Henri Nargeole was part of a tourist expedition to observe the wreck of the Titanic. Communication with Titan was lost 1 hour and 45 minutes into its dive to the wreck site. Authorities were alerted when it failed to resurface at the scheduled time later that day.

Personal Submersible 

A dildo.

Janice's embarrassment found new heights when her friends burst into her apartment yelling "Happy Birthday!" only to find her alone spread eagle on the couch and right up to the finger-tips with her new personal submersible.

Submersible 

When you eat a sandwich in the shower with the water running and it just starts making the bread soggy, but effectively ridding of the crumbs as well

Person 1: What if we just had a submersible together? You know, to celebrate good times?
Person 2: No way. That is a waste of perfectly good bread.
