This post is a list of memory feats for the mnemonist or the mnemotechnician. I am not including pseudo memory feats or ‘magic’ tricks that rely on mnemonics.
Here is a list of the classical memory feats:
Day for any date
Saying the alphabet backwards
memorising lists of objects
Memorising serial numbers on bank notes
Memorising a deck of cards
Feel free to add more as you think of them,
