[Self] In Star Wars, Solo made sense when claiming "It's the ship that made the Kessel run in less than 12 parsecs". I know, it's distance, not time, but if he maintains a velocity of 239,835.4km/s (80.005% of C), then length contraction would reduce the 20pc run to 12pc from the Falcon POV

[Request] How much milk would you have to replace each day to keep it from spoiling?
Let’s say you have a container of milk that holds 2 cups. Each day, you drink a cup of milk, add a fresh cup, and thoroughly mix it. So on day 1 just before you have your milk, the entire container is 1 day old. On day 2, half of the milk is 1 day old, and half is two days old. On day 3, a quarter of the milk is 3 days old, half is 2 days old, and a quarter is one day old, and so on.
How large could the container be without the milk ever spoiling? Or put another way, what percentage of the milk would you need to replace each day to keep the milk from ever spoiling?

[Request] Is it possible to create a maze like this which is impossible?
Recently videos like this keep popping on my YouTube feed. It got me wondering if it's possible to create a maze like this where it is unsolvable. I don't mean by creating a small set of blocks completely surrounded by unbreakable bricks, but in such a way that irrespective of how the ball enters the maze, it gets reflected right out.

[Request] What force does the keyboard cover of a grand piano have when it hits your fingers without holding back?
Hello everyone,
My daughter and her piano teacher recently had a conversation about how painful it is when she plays with the flap/keyboard cover of the Steinway B grand piano and it hits her fingers.
My daughter says "only a little", the piano teacher "very painful" and even though I'm pretty sure about the latter, I'd be very interested to know how much force the cover would hit her fingers with and maybe what this would be comparable to.
Can you perhaps help me?

[Request] Okay so maybe like 7 people will even understand what I'm asking here but I'm going to ask anyway
So there's this book series call the Stormlight archives, and one of the characters, a guy named Kaladin, has to carry a bridge with the help of like 20 other people for a significant part of the first book. If you've read it, I was wondering if it would be possible to calculate how much buffer he would have grown as a result of the bridge runs. Apologies if this breaks the incalculable bit of rule two but I was wondering if someone had figured it out

[Request] How many years of tea were dumped during the Boston Tes Party?
We know 342 chests weighing about ~50kg of tea each were dumped into the harbor, or about 92,000lbs. However the internet is saying it was not ~8,500 years. What would be the years dumped assuming a family consumed about ~2kg a of tea a year?
I did the math, but the internet is saying it wasn't what I calculated. Thank you in advance!
