Mnemonics (Memory Aids)

How to make a better mnemonic:

1.  Make the remembered sentence more easily remembered: shorter, more logical, or more funny or more silly. If this sentence is too difficult to remember, you might as well just recite the actual set of words that you want to remember. 
2. Each word reminds you of a word to remember. Instead of matching just the first letter, match two or more letters, better yet make it rhyme or echo the set of words to be remembered. 
3. Perhaps add a picture, to visualize the idea.Example: For remembering Methane, Ethane, Propane, and Butane
    Use: 
   
   Meet Ethan, Professional Butler.
   
   MEthane ETHANe PROpane BUTane
   
   OR
