These guys from Utah and Indiana tested what could be the world’s smallest submarine, and the occasion was entertaining but stressful.
The submarine was previously cleverly crafted, and the time came to put it to the test.
But, as you’d expect, it wasn’t exactly a straightforward process.
The test run came with its challenges but was equally very amusing as events unfolded.

Boats come in many forms and in all different shapes and sizes.
From mega superyachts to small sailing boats – there are many different kinds on offer in a large price range.
For example, the world’s largest sail-assisted yacht costs $300 million and has a helipad and a glass-bottomed swimming pool.
But this jaw-dropping flying boat may be one of the most impressive creations we’ve ever seen.
Alongside boats that float on top of the water, submarines also dominate the waters, which have many different uses, and they don’t always have to be from huge companies.
These guys from Indiana and Utah tested what could be the world’s smallest submarine, and well, it was entertaining, to say the least.
The clever contraption was submerged into the water, ready to get some action, but first, the guys on the HeavyDSparks YouTube channel had to figure out how to work it.
Let’s be honest, traditional submarines must be hard enough to navigate, let alone one like this.
Two guys got into the submarine ready to give it a good run for its money, but a sense of stress was felt.
The small cabin of the boat filled up with water, and the air quality was low, so the use of air tubes was needed.
After the initial test run, one of the guys swam back in for more after figuring it out a bit better.
“It’s such a unique little experience, it’s not like you’re just getting in, pushing a button and going, it’s not that easy,” explained one daredevil who was in the prime captain position of the vessel.
“You’ve got to understand fluid dynamics,” he continued.
Take a look at all of the submarine action below – would you ever dare to try something like this?
