Each car battery provides ~12V, but when you connect 400 batteries, everything depends on how they’re wired:

• Series = voltage adds up → potentially thousands of volts
• Parallel = current adds up → massive amperage

In this case, the system is designed to push an extreme amount of electrical energy through a single steel bolt. When current flows, the bolt resists that flow—and that resistance converts electrical energy into heat.

Enough current + resistance = rapid heating, glowing metal, or even structural failure.

This is the same core principle behind everyday tech:
• Electric heaters
• Fuses (designed to melt under excess current)
• Industrial power systems

Scaling up just makes the physics impossible to ignore.

Drop your guess before watching: does the bolt melt, explode, or hold steady?

Share this with someone who loves wild engineering experiments, and remix it with your explanation of what’s happening.
