You know how canaries were historically brought into coal mines, because if the mine was full of carbon monoxide the canary would die first and the miners would be able to escape before they died too?
I just found the greatest thing.
This is a canary resuscitator.
When the miners notice the canary getting sick with carbon monoxide poisoning, they can close that circular hatch so no more gas gets into the canary cage, and open the valve on that oxygen tank to keep the canary breathing. In other words, they made a spacesuit for birds.
By immediately giving the canary access to clean air, the miners can save it from the poison. The bird lives. To be clear, this is not for economic purposes, this was specifically created because the miners felt bad and wanted to save the bird.
Isn’t that just the perfect demonstration of what humans are like? We started sacrificing small creatures to save ourselves, and then felt bad and spent our valuable resources on saving the critters too. Because yeah the canary was the only way to test for CO, but it’s a living creature too, dammit!
if you refuse to get the vaccine the government should sneak into your room after you go to sleep and take out the little chip in your neck that makes the supermarket doors open when you go near them
on the first day of class my astronomy professor asked us why the night sky was dark. if our universe is infinite, how can there be spaces between the stars? he didn’t answer the question until the last day– because our universe is relatively young, and is still growing. it is finite. not enough stars or galaxies have been formed to fill up the entire night sky.
but what that means to me is that somewhere, in an older universe, the night sky looks like a tapestry of diamonds. somewhere darkness is pale white and glittering. imagine being so surrounded. i haven’t gotten that image out of my head ever since– you could never navigate under such a sky but god it sounds lovely
That’s because pea flower tea works naturally as a ph indicator! It will turn magenta when mixed with acid (lemon juice) but will turn cyan green when mixed with something alkaline (baking powder, bleach etc.)
