Here Simon explains one more effect he has played with at home, the Magnus effect.
How does a periscope work? How does light travel through a periscope? How can you make a periscope yourself? Simon answers these questions in the video:
Also tried to trace the motion of light inside the periscope using a laser beam:
Oops, the Magformers are back in our life. I thought that Simon was over Magformers (which he built with excessively when he was six), but he has picked them up again and taken them to a new level. He seems to be using Magformers to illustrate his increasingly philosophical thoughts in the pauses he takes between lessons and programming. Yesterday, he was quite disturbed after building with the mirror piece for a while and said: “What if two mirrors reflect each other? Would that stop time?” He added: “Just for safety, I’m going to put the mirror in the box. Never, never ever put two mirrors opposite to each other!”
He hasn’t made it interactive yet though. This was the original plan but he got stuck.
