I haven't done many home experiments before and I thought a cloud chamber would be a fun one to start with. I want to test the radioactivity of various household objects. I have taken an intro chem course in uni so that's my highest level of chemistry so far.
I read some articles that tell you how to do it, but I think being able to do it doesn't necessarily make it a good idea. I have volunteered as a lab tech for my school so I am used to doing experiments and I have even handled some highly concentrated acids before. My only fear as far as this experiment goes is handling the dry ice. I have never handled it before and I'm worried about how I would dispose of excess and store it while conducting the experiment.
I spent some time learning about superconcentration and how it applies to the experiment. My current understanding is that the top of the chamber is heated and the bottom is cooled. Water vapor acts as a solvent for the solute (gaseous 99% isopropyl alcohol). The alcohol becomes superconcentrated at the top of the chamber and in its superconcentrated state is very fragile to change. When the ionized radioactive particle is emitted from the radioactive object, a droplet of moisture forms and falls when the ionized particle interacts with a molecule of superconcentrated alcohol. I don't know why this interaction causes a droplet of moisture to form. I know that water vapour must cool down to change to a liquid state, but I don't know what causes it to cool down. Does anyone know?
Any and all advice is appreciated!
Hi all,
Out of curiosity, I did an experiment: migrate a Rancher/RKE Kubernetes cluster "live" from a cloud provider to another, instead of backing up in the first cluster and restoring in the new one. It was fun and I thought I'd share it :)
The minute long video easily found on YouTube shows the video Bob Lazaar had on an old tape. Found by producer Jeremy Corbell.
Could someone explain ELI5 what this actually shows? Is it the green light that is distorted in a wavy pattern that’s unique I.e. the material is bending the light?
Also in the documentary on Netflix Jeremy eludes that the video itself doesn’t “mean shit” is that because it isn’t long enough or can’t be collaborated as to when or where it was taken etc??? Or is it that it could have been altered?
Thanks to all
I knew the name of this thing when I was smaller, but now I completely forgot. Edit: Solved!
We want to plan an experiment for the day of Sentinel-2 image acquisition. This experiment costs labor/resources, so if the image has cloud cover then it is a waste. Can we look at weather forecasts to know if the cloud cover will be low? Anyone dealt with this before?
