A roomba - in case you're wondering - is a robotic hoover that scuttles along the ground and basically scoops up random bits of fluff. They're pretty big in the US. We've yet to see one in real-life.
So, the folks over at RoosterTeeth went ahead and did what anyone would do with a roomba. They strapped a knife to one end, a balloon to the other and set them to fighting.
The results are explosive.
As we watched this, we couldn't but notice that nobody was wearing any kind of protective shielding on their feet. That's just asking for trouble. In fact, the whole experiment is totally unadvisable. We totally do not recommend you try this at home. Ever.
