Determining if an item is made from polypropylene (PP) can be accomplished through a few methods. One is to check for recycling symbols; PP is often marked with a recycling number 5 inside the chasing arrows symbol. Another method is the float test; as PP is less dense than water, it will float when placed in water. This method, however, isn't foolproof, as other plastics can also float. A more conclusive test is the burn test, though it should be conducted carefully and in a well-ventilated area. When burnt, polypropylene melts and burns slowly, dripping while producing a faint, sweet smell, and the flame is usually blue with a yellow tip. Unlike PVC, which emits a pungent odor, PP's burning smell is less intense. Always use caution and appropriate safety measures when performing a burn test. Identifying the material correctly can be crucial, especially for recycling purposes, as mixing different types of plastics can contaminate the recycling process.

The pipe symbol "|", also known as a vertical bar, is a character used in computing and programming for various purposes. It is commonly used in shell environments and scripting languages to pipe the output of one command as input to another, enabling the chaining of commands or functions to process data in a stepwise fashion. This allows for efficient data processing and manipulation without the need for temporary files. Additionally, in programming languages like C, C++, and Java, the pipe symbol is used as a bitwise OR operator to compare bits of binary numbers, where if either of the bits is 1, it returns 1. In regular expressions, the pipe symbol acts as a logical OR, matching patterns on either side of it. Its versatility across different contexts makes it a powerful tool in the hands of programmers and system administrators.
