Contribution
It introduces practical, accessible procedures for generating and verifying liquid oxygen in educational settings without specialized equipment.
Findings
Successful small-scale liquid oxygen production demonstrated.
Effective identification methods for liquid oxygen versus liquid nitrogen.
Accessible procedures suitable for classroom demonstrations.
Abstract
In this article I explain in detail a method for making small amounts of liquid oxygen in the classroom if there is no access to a cylinder of compressed oxygen gas. I also discuss two methods for identifying the fact that it is liquid oxygen as opposed to liquid nitrogen.
