Kaylin and Kiersten have been having prank wars back and forth for more than three years. "Kiersten once filled my room, closet, and bathroom with about 1,500 balloons and completely filled my car with packing peanuts. So, now, all of our friends and family always ask to see our latest prank! I posted the upside down bedroom on TikTok, Instagram, and Facebook, but had NO idea that it would go this viral!" Her video of the prank has more than 11 million views on TikTok.
