How to memorise the metals activity series and what they react with

To easily memorise the activity series in chemistry, i found a mnemonic for it
Popular-potassium
Scientist-Sodium
Can-Calcium
Make-Magnesium
A-Alluminium
Zoo-Zinc
In-Iron
Low-Lead
Humid-Hydrogen
Country-copper
More-Mecury
Satisfactorily-Silver
Pleasant-Platinum
Good-Gold

So if you memorise that simple mnemonic of popular scientist can make a zoo in the low humid country more satisfactorily pleasant good.

Also you should know Lithium is at the top,its the most reactive metal, maybe you can put Lithium and start with little popular scientist.....

Metals above hydrogen can displace hydrogen

Metals very high like potassium,sodium and calcium reacts with cold water and acids, as it goes down the activity series it needs warm water like magnesium reacts with warm water when it reaches iron it react with steam, when it goes below hydrogen they don't react with water.
