Can You See Cosmic Rays on Hot Drinks?

[jamie]

You always find the most random but interesting experiments

[wlockuz]

Your ability to find the most mind blowing things in the most mundane things in life is amazing.

Thanks. Now my friends think I'm weird. "Why do you keep staring at your hot chocolate? "

[TheBackyardScientist]

that's pretty cool, I cant believe i never noticed that before!

It’s nice when people present things as “first described”, “first explained”, etc instead of first discovered for things like this.

Looks like this is a great idea for the slow mo guys to film

[Konarcoffee]

I'm always impressed by how novel your videos are

[hedwigs]

Love how he's just calmly speaking while his geiger counter is losing it
Edit: God yall have no sense of humour

Very cool experiment! I also suspected that the levitation is caused by a tiny electric charge :)

[charlesblithfield]

Your curiosity is infectious and your ability to relate complex scientific ideas to everyday life is unique.

Highly recommend youtuber Posy who did a video on this called 'Hot water colors'!

It would be neat to try this in a really shallow container. That should suppress convection and you could see if crack patterns still formed.

"These are blocked by the platsic...."
The Geiger counter starts screaming. XD

THIS is the content I love from you. Seriously please do more of this. You're taking something that is genuinely interesting and doing some actual science to figure out what the heck is going on. One of your best videos to date.

This is just a guess, but may be the reason water droplet form on top and just doesn't mix with rest because, water droplet are pure water while rest is mixture (tea or cocoa). Which result in difference in composition, thus slower rate of diffusion.

You have one of the best science channels. Always coming up with original and random topics that are both fascinating and educational. Keep up the great work!

1:05 Well the droplets are incredibly light, light enough to float around in wind. And the droplets have to touch the bulk liquid, but air is in the way. Regular water will also float around on regular water in some conditions

4:23 “but these are blocked by the plastic”
Proceeds to beep crazily

I've been wondering about this for some time now. Thank you for covering it!

I went through this *exact* thought process when observing this very effect on the surface of my morning coffee. Ended up concluding that the convection processes would dominate any movement compared to the relatively weak effects of any possible cosmic rays.

I'd love to see you repeat this experiment with an alpha and beta ray source to be sure though!
