????Today's topic: Problems that even physicists can't solve???? Hello, subscribers???? Today, I brought you a video that I filmed in collaboration with the Geekble channel! I showed Professor Kim Beom-jun the problems that the Geekble channel prepared. I also included a little bit of the professor's cute appearance, who was more focused on the cookies???? than the problems. ???? Then, I hope you enjoy today's video. ????Timeline???? 00:00 Intro 01:08 How long can you stack the sticks? 07:31 Can you fit a cookie through a small hole? 10:29 Perpetual motion machine verification time
