You are constantly bombarded with invisible cosmic rays, but this upcycle jar can make them visible. Whoa. Let's talk about some everyday awesome science. This is a homemade cloud chamber. The mist you see inside is isopropyl alcohol. This streaks running through it other tracks of cosmic rays and charged particles. I put black tape on half the container, glued a sponge to the top, and soaked the sponge in isopropyl alcohol. Then I closed the lid and turned it upside down into a bucket of dry ice. I then placed a hand warmer on top. The heat at the top of the container causes the isopropyl alcohol to evaporate. But the dry ice keeps the bottom half of the container cold. This causes the isopropyl alcohol to condense into these tiny mist particles. When cosmic rays and charged particles fly through the mist, they disturb an ionized gas molecules inside, causing the mist to come together into tiny droplets, creating the tracks you can see. It's easier to see if I put the cloud chamber in a dark area and illuminate it with a flashlight. Big negatively charged muons leave large tracks, while electrons and positrons leave tiny curly ones. This is so cool!
