Is it possible to build a cloud chamber by using normal ice instead of the usual dry ice? The temperature for dry ice is about 200$K$ while it is about 270$K$ for normal ice.
This link here describes how to build a cloud chamber without dry ice. Cooling is provided by an air duster ("The difluoroethane it releases is cold enough to supercool alcohol vapor, which is what you need for a cloud chamber.")
The other cheap method (cheap if you have a tech-junk collection: CPU heatsink and peltier cooling modules) is this: https://www.google.com/search?q=pelter+cloud+chamber
A local hobbyist did it with two stacked thermoelectric coolers, but mentioned that even a single one can work, if the heat sink can keep the temperature low enough, see http://www.nothinglabs.com/cloudchamber/
Using water ice and salt combination I have been able to get to $-21^\circ\rm C$. I have seen a demo of doing a cloud chamber with water ice online somewhere. I'm looking again today.
