4 liters of tap water at sea level. Must bring it to boiling and it takes forever. How fast is the fastest it could it be brought to a boil without melting the pot holding it?

How much would that cost?

I was thinking about this meme of legolas today. (For those unfamiliar, it's about how large legolas' eyes would have to be to see the distances he does in a non-magical setting).

I was thinking, how large would the human eye need to be to see bacteria with the naked eye? (Assuming no changes to the mechanics of the cells like rods and cones inside the eye. purely from having a larger lens.)

EDIT: 345 FEET — football on the brain!

Trajectory is tough to determine but I’d estimate the ball lands 16 feet higher than it was struck. The right field wall is 8 feet tall, and the guy looks to be another 8 feet higher than that.

The video was made in Brazil, he mentioned that the plastic bottles are pressurized to 100psi

What would be the autonomy in your opinion?

I’d also like to do the tomato fight thing, please factor that in.

How much work is the helium doing to decrease friction with the road?

Bonus points for the force required to accelerate me in the two metre-ish space between the seat and the blades, and also the effect that acceleration would have on the human body.

On a serious note I think it is a bad idea to attack other counties especially the ones who control oil. I am against war and against innocent people dying.

My partner is making homemade animal collars that are adjustable. We noticed that the longer the initial string, the larger the variation in collar length. Two specific examples:

We started with a 21 inch piece of paracord, and it ended up being:
9.5 - 7.5 in variable length

We had another one that was 26 inches and it ended up being:
12 - 8.5 in variable length

I am not great at math but know enough to know that it could be some sort of (non)linear(?) curve or something that relates the initial cord length to a set of high and low ends for final length.

I also know there is probably a small amount of variation based on the knots and amount of beads on them, but that should be small enough to be negligable I believe?

I was just hoping someone could figure out the math to know what the variable lemgth will be based on starting cord lengths?

Thank you in advance!

Is it posibble with the current volcanic eruption of anak krakatau in Indonesia will have the same effect as krakatoa explosion? Will the volcanic ash in the sky be enough to reverse global warming?

The calories in the whole thing, plus the size of slice he serves.

Assuming the 112 MPH speed was measured as it left the bat, approximately how fast was the ball going when it hit his hand?

Lead foil is apparently available even thinner, but I'm assuming it would be difficult to get large sheets at ultra-thin gauges.

I found this interesting and thought maybe you nerds would too.

Is this like, a question that applys to here, like, how many would need to be twisted together to make a stable functional guitar string

Kinda curious after a friend made this a question in this head
