Continuing our "what happens when you drop stuff into stuff?" series is this short video segment from the BBC. As with dropping a magnet through a copper pipe, many of you probably know what to expect, here. But it's nonetheless cool to see. Mercury is so beautiful; such a shame it's also so toxic.

This simple demonstration of eddy current braking (Wikipedia) will probably be familiar to many of you, but this video from YouTuber JamesRB1995 is a short, well-shot, impressive documentation of the effect. Keep in mind that copper is not ferromagnetic, and there is no direct magnetic attraction going on here.

Kinetic Sculpture Manipulates Rare Earth Magnets
The Aquarius Habitat supports Saturation Divers at a depth of 47 Feet Sea Water. The commercial diving industry conducts saturation diving to much greater depths utilizing chambers on board a Dive Support Vessel (SDV) and a Diving Bell for lowering divers to the sea floor. One of the largest and most modern saturation diving systems in operation today is the DSV Skandi Arctic. Aquarius Reef Base's Operations Director, Saul Rosser, also happens to have been heavily involved in the design of this system which can take divers to 350 Meters Sea Water (1,150 Feet Sea Water). Discovery Science recently produced an episode of their Mighty Ships series on the Skandi Arctic and it can be viewed at the following link:

Time to get your quill and ink out pupils...good luck!
This week I am giving the last in the semester series lectures on technology's impact on us as part of the Osher Life long learning academy. On Wednesday I will also be giving a science cafe talk.
