I like to eat grapefruit.
I prefer to peel them like oranges and eat them like apples.
I dislike the way the juice runs.
Now before someone says: "Thats why they are cut in half and eaten with specific spoons" ,
I would like to emphasize that that idea takes a bowl, concentration, and two free hands.
So what I want with my grapefruit is a soft hemisphere of plastic, silicone preferably, which allows me to hold the grapefruit. Like a catchers mitt for juice. It would work for other fruit as well, of course - ( peaches, anyone?), and would be quick and easy to use and clean.
Adding a small stiff curved tab to one edge - about the size of a teaspoon's blade - would
facilitate the peeling process as well.

Anyone want to run with this idea?
Calling it the Fruit Cuddler might attract the wrong customers, though.

Would it be possible to grow a human embryo inside an ostrich egg?
If the egg was fertilized, but the blastoderm excised, replaced with a human egg cell?
I'm wondering that if because of a common Terran heritage, if the molecular hooks and cues would be the same, so that the placenta would form attached to the egg yolk, and feeding from it.
At a first guess, oxygen demands would become a problem. Now if the egg was carefully decanted into a beaker, kept at human incubation temperatures,and a oxygen perfusion rig attached...
As the yolk is consumed, fresh supplies could be added via injection.

This would approach the egg as a development machine which could be hacked to grow other things. Its already done with virii and bacteria, after all.

This could be tested with chicken eggs.
