Poland's Hubert Hurkacz, ranked No. 29 in the tennis rankings, participated in #thefloorislava challenge and did a pretty good job with his attempt. The FllorisLava challenge is where one person yells “The floor is lava!” and then starts counting down from five.
The other person must be completely off the ground by the time the counter reaches zero. After doing the challenge, Hurkacz nominated some of his fellow tennis players Marek Wojciech, Michal Przysiezny and John Isner to do the challenge as well.
