I can't remember using it to centrifuge blood samples, but maybe your childhood was different from mine.
We used it to demonstrate centrifugal forces in elementary school by spinning one and putting drops of food coloring in the center. They were made of lightly-waxed parchment paper so you could see a trail it left behind as it got flung off.
I'm just surprised it took this long. That particular lesson was... 26 years ago for me.
Well why didn't you tell the world about this 26 years ago. Heck, why didn't you tell the world 2 days ago?
Then, much like now, I'm too busy with minerals and the inordinate amounts of money people will pay for them.
It must be tough having no free time over 26 years. Hope retirement goes well for you!
Retirement? That doesn't happen to workaholics like myself.
Is posting to Hacker News part of your work?
It's what I do while I'm waiting for 4-ton boulders to get moved out of the way with heavy explosives.
You should have used that time to invent the technology that you knew about for 20+ years.
Why me instead of someone else? Someone else needs to have success in life. I'm too busy getting you guys the lithium you need for your portable devices because you can't be bothered to do proper recycling.
That's quite noble of you. I just hope you aren't also sitting on the cure for cancer, so you don't hog all the glory for humanity.
