I'm not fond of all the guns and ammunition, but that's boys for you. I find the human bodies fascinating, if a little squirm-inducing. Food items are just weird - surely we've all seen half a sandwich before.
How in the world do they cut all those liquid things in half? And the barbecue grill, for that matter!
I think the two most surprising to me were the visa card and the mechanical calculator. The bowling balls were interesting. I think the first one shown must be some fancy new kind and the second the old kind that can frequently be found in 2nd hand stores. I'm not sure that "banana being cut in half under a microsope" is really that. I suspect it's actually a closeup of a banana trunk. The gif of the key in the lock is mesmerizingly elegant. It's all fun and interesting.
this would be a cool site to show agnes how some things work/get her interested in how they work or what's going on inside of them - though i think i'd have to go through it before, i wouldn't want to see some of the inside-a-human pictures yet (though then again, she might find them less squirm-worthy than i do, you never know) ...
