Physics is always interesting...

This photo contains one of our physics teacher, extraordinary courage and fun. This photo was taken when we were learning the topic of pressure. I was amazed when I saw this pic because how can a person would dare to put some screws facing his chest and make someone stand on them and hope that those screws on his chest wouldn't sting. This is a courage beyond imagination. Of course he also wouldn't dare it unless he knew that because of the physics laws they wouldn't sting. I wanted to share this amazing photo with you all.
