To showcase just how powerful cars are, as well as produce some tremendous controlled explosions, this US man wired 400 car batteries together in one of the most extreme science experiments ever.

Nowadays, car batteries are much more powerful than ever before.

But as we move to an era powered by currents surging from lithium-ion and sulphur-based power units, what happens to the old voltage vacuums that used to keep your stereo and AC on?

Well, it seems a US man is collecting them with the sole purpose of blowing up metal – in a controlled environment, of course.

Wiring up 400 car batteries for some YouTube chemistry

Known as ‘styropyro’ on YouTube, the young US man is a ‘science maniac’ by hobby and a chemist by trade, and he’s built some of the biggest lasers ever seen on the internet.

So, in a world where old car batteries are becoming redundant, the mad professor decided to gather as many as he could find and create a lightning strike, and show what happens to certain metals under this pressure.

With 400 car batteries, capable of over 160,000 amps, the YouTuber first had to create a monstrous switch that could withstand such voltage, as you can’t buy one that powerful from Amazon or Alibaba.

So with over 1,000lbs of copper strapped to modified log splitters, the contraption was set.

But why did he choose car batteries instead of other electrical circuits? Well, the YouTuber claims that they offer nearly as much power as anything else, but can sustain it better than anything else.

“When it comes to making huge currents, most people think of using capacitors.

“But interestingly, car batteries don’t fall that far behind in terms of max currents. The benefit with car batteries is that they can dump those currents for far longer than a brief pulse,” he said.

So after rinsing cars for their power, it was time for the fun to start.

Let the most extreme science experiments begin

All of this was in a bid to make explosions that even Fast & Furious would be proud of.

First, he showed how the power can warp a pipe, as it can be concentrated enough to bend materials.

After a few fails, due to the power simply annihilating the pipe rather than bending it, the creator his the sweet spot and managed to crush it with magnetic pulses.

In the midst of this, though, he tested other materials such as tungsten rod, titanium, and bismuth, all of which went boom.

The finale of the extreme science experiments series saw the YouTuber use Ferrofluid to make a huge fireball explosion, just for the fun of it, and there’s no denying the final picture wasn’t spectacular.

“I think it’s the coolest thing I’ve ever filmed in my life. In the span of a10th of a second, nearly the entirety of the dish of ferrofluid was slammed up against the pipe while the total circuit power rose to over 10 million watts,” he said.

By the end, all of the car batteries were still intact and could be reused for other purposes or placed back into a gas vehicle.

But what we really want to see is the YouTuber use this tactic to try and cannibalize the unkillable Toyota Hilux, which has withstood countless experiments in the past.
