Not content to have a useless, store-bought Mjolnir, one man set out to build his own.
Caleb is a man with vision. He knew he would never be satisfied with a Thor hammer that couldn't shoot lightning. So he managed to get a Tesla coil small enough that he could fit it inside a hammer he'd designed himself. After a bit of experimenting, he struck gold. Or lightning.
What can it actually do? Well, according to the video, it has the ability to "light up any fluorescent bulbs around, scare children, and leave the smell of ozone behind. It is super fun!"
We only wish there were some way to scientifically calculate how super fun things are. We imagine this hammer would be off the charts.
