Maddie and Mackenzie Ziegler are coming in like a wrecking ball!
The star sisters joined YouTube’s Slow Mo Guys for a rubber band ball challenge that involved rolling giant rubber band balls down a hill and crashing into as many objects as possible- and watching it all back in slow motion, of course!
It turns out the girls won by quite a bit. In fact, there was a difference of about a million points, so you could say they absolutely smashed it, just like they smashed an entire car door in the process.
Watch the super cool video below!
