Question: Sir, you talked about mini particle detectors called spark chambers which you told can be easily made. How to make it? Is it simple enough for me to make?
construction, particle detector, spark chamber

The simplest spark chambers are *very* easy to make. If you have the equipment, you could definitely make a very simple one quickly and easily.
There are actually some neat instructions on how to build the simplest kind of spark chamber here:
Even this should be sensitive to alpha particles, i.e. systems of 2 protons and 2 neutrons.
It’s not too difficult to build more complex spark chambers like this, but a lot more expensive:

I still personally think that cloud chambers are even more easy to make than spark chambers.
You just need a slab of dry ice, some propanol, a clear plastic box and a bright torch. I’d have gone with this for your project David! http://www.lns.cornell.edu/~adf4/cloud.html

True, but cloud chambers aren’t of any serious scientific use any more. Spark chambers still are.

I’m really not sure your idea is practical David. There are a lot of regulations surrounding the safety of electrical equipment in schools, and I’m pretty sure that exposed copper plates with a 1 kV potential difference across them violates most of them. If you win you might get *one or two* spark chambers built, with some luck though! I think that you could make cloud chambers much more easily, however.
what experiments could you do with a mini particle detector in schools?
