I've tried the can opener one too, and failed. Also tried the brownie in a mug (or one of the other variants) and it was awful!
But quite a few of them are awesome ideas. I'm partial to the nutella ice cream one as well!
I'm not sure about asking your friends to pose for a photo with stuff they've borrowed though! Not really my kinda thing, and i can never find photos when i want them (or remember that i've taken them in the first place!)
Also not really sure how learning how to tie a tie is an efficiency tip?
