- 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.
Thanks Anthony
Pleasure Mark and thanks for supporting the channel as ever!
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 th-cam.com/video/ZMByI4s-D-Y/w-d-xo.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 th-cam.com/video/onZDAKJq6z4/w-d-xo.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!
