Pro tip: You can just eat the ingredients straight from the fridge.

Bacteria can thrive in some amazing places: Deserts, Antarctica, volcanoes, underwater volcanic vents. Basically everywhere on earth, even the most extreme places. So for any one property of the Mars enviroment, there will be a bacteria that can survive it. I'm going to go out on a limb and say there is probably a bacteria that can survive somewhere on the surface of mars. If there isn't, then it probably won't take long to mutate, and evolve into something that can survive there. But the chances of that bacteria being in your potato are pretty slim. Earth top soil is completely different to wherever that potato will land on Mars.

If you want to send potatoes to mars without accidentally introducing bacteria, then yes, there is a risk. On the other hand, if you want to seed mars with viable bacteria, you would do better by being selective about which bacteria you send there, and sending a food source more appropriate than a single potato.

I've discovered that I'm good at herding flies.

I start by turning off lights sources including the TV, and closing all the doors and curtains except for one open window which is now the brightest, and therefore most attractive destination for the fly.

Then I just stand so that the fly is between me and the window. I wave my arms out sideways, kind of like semaphore, and it discourages the fly from flying towards my body and my hands, and can only avoid me by flying in the direction of the window.

It doesn't work at night since turning the lights off means I can't see the fly, and with the light on, it just flies to the light, lol.

They also don't like wind, so if there is a breeze outside, I make a stronger breeze inside by swinging a towel like a helicopter blade, and it makes the entire room very undesirable for the fly.

When I was a kid I would just wait until the fly was bouncing itself against the window, and just catch it in my hand, then throw it out and open window.

It also helps if you keep your house free of stale or rotting food smells.

This skill has dramatically reduced the number of flies I've killed by swatting.

The system takes advantage of the heat difference between Earth's surface and the night sky, with the ground radiating much of the heat it captured during the previous day.

It's not a reverse solar panel. It's not a solar anything. It requires a difference in heat... So it generates electricity in the same situation that a sterling engine uses to generate motion. Could you put one on a diesel generator to turn the waste heat into more electricity?

Does it have anything in common with those weird little solid state heat exchangers Peltier elements? Wait, are they actually, literally peltier elements?

You have peanut butter named Jif? That's weird, where I come from Jif is an abrasive cleaner.

...Is your peanut butter gritty?

Any flies that fly into my house are given a chance to leave. If I can herd them out the window, they get to live and make lots of new baby flies.

On the other hand, their chances of getting a close up view of the fly swatter increase exponentially with every minute they spend refusing to leave and ignoring the fact that I'm literally showing them the exit.

Have you heard the one about the cannibal who passed his ex in the jungle?

I like how the Arabic word for ape is the same word that they use for monkey, but the artist cleverly drew one with a tail, and one without.

Or maybe just an om. Unless you fill it with cheese and pineapple, then it's an om-nom-nom.

I'm not the OP, but I couldn't leave y'all hanging with no moss.

Groke - An old Scots word that refers to someone who stares at you while you eat, in the hope that you’ll share your meal with them.

Heavy Metal (1981) is often compared to Fantastic Planet. There's no son, but lots of the other things you listed match.

This is beautiful

Make her a little leather helmet.

Go on then, I'm all ears.

Duct tape and cardboard solutions to questions like "How do I get these two pieces of photography equipment to work together?"

Wikipedia says that they "lack short wavelength sensitive visual pigments in their cone cells", so they don't see blue as well as we do... Which isn't surprising really.

My cat could. But only because I would rub my fingers together to make a faint noise, so they could tell where my hand was without looking.

It significantly reduced the number of surprises, and they felt a lot more comfortable around me.
