Supersaturated water/methanol mixture provides the clouds. Most of what you're looking at is background particles. We also used a couple needle sources (Pb-210 and Sr-90). More info at our website: www.mip.berkeley.edu/physics

  • They're trails of gas charged particles leave behind. The particles are mostly muons which are leptons, like electrons. They're created in the upper atmosphere when high energy EMR (Cosmc Rays) collides with molecules of atmospheric gas. They aren't being created by radioactive decay, as there's no radioactive source present.

  • The little jets of white stuff are subatomic particles right?

  • If you did the same experiment with nanoscale piezoelectric materials instead of alcohol, would you get an electrostatic discharge? I hypothesize the huge electrostatic discharges that take place in the mouth of erupting volcanoes, and in ice /cloud formations (thunder storms) are the result of piezoelectric crystals inter-reaction with cosmic rays. Ice is piezoelectric and in a volcanic eruption silicon based nano crystals would be forming as hot gases are ejected into the atmosphere.

  • What are you using as the particle accelerator

  • looks like non-stop collapsing ground

  • @nkip9230 The first minute of the video shows only background radiation, so yes it works quite well. And you really don't need to worry about the minimal shielding effects of the building.

  • @BraedonR

    Is this experiment successful then with out a radioactive source being present? My physics teacher and I were thinking of building one. My only concern is, does a school building itself reduce the amount of cosmic rays?

  • MINI RAIN FTW!!!

  • kia lush scene he yar. i mean it is awsome.

  • No, just atomic particles. You're seeing the same cloud condensate around it as the alpha or beta radiation/particles hit the vapors.

  • Is this level of bombardment the same deeper in the earth? Would I be protected from this miles down?
