- Having seen others try the Aluminium Foil Ball Challenge I thought I would give it a go. Not too difficult and a pleasing end result but on and off it took me two years to complete! Let's see how I did it.

All a bit of fun and managed to get a little bit of physics into it! Thanks as ever for watching.
This has given me an idea how to make something (not a ball) I've been thinking about for some time, foil will work but I think I will be using a hydraulic press not a hammer.
Look forward to hearing more...!
Not _quite_ as spherical as ua-cam.com/video/ZMByI4s-D-Y/v-deo.html (!) but pretty good nonetheless. It would be interesting to see what the material is like in cross section close up, e.g. with a scanning electron microscope. A good proportion of it must still be air with a bit of oxide too, but I wonder how it's distributed.
Yes, I remember that sphere when it was discussed in Physics World a few years ago. Not quite that close indeed! I really would not want to cut it in half but would be interesting to see what it looks like. Ultrasound would just produce an mess of an image I think. Adam Savage did a good job with the water jet cutting ua-cam.com/video/onZDAKJq6z4/v-deo.html I really feel that, whilst there must be lots of voids, dirt/oxide etc. the layers may well have got close enough to form metallic bonds. It was a fun project regardless and thanks as ever for your interesting observations. Do keep them coming!
Thanks Anthony
