Most Physics teachers tell their students about the law of gravity by recalling the story which happened to Mr Newton as he was sitting under a tree. But none of them have ever used a lovely video like this during their lesson presentations! However, they might be a much better manual for up-to-date students than reading boring school books - just imagine yourself being a student who was taught the law of gravity by using these awesome pranks. Doesn't it sound amazing? We hope it does!
