Some of JK Rowling’s ingenious magic objects and spells have real-life counterparts. Can you guess which of these Harry Potter spy gadgets are also available for muggle use?

1. The Invisibility Cloak

Harry would have a much harder time sneaking around if someone *ahem* Dumbledore hadn’t decided that he should have his father’s magical cloak. But how likely is it that a muggle could become invisible just by changing his or her clothes?

2. Hermione’s DA Coins

The members of the DA know when to come practice their defense against the dark arts spells thanks to Hermione’s coins, which turn warm in members’ pockets when she wants their attention.

3. Sneakoscope

If Harry had paid more attention to this gift from Ron, he may have figured out sooner that Ron’s pet was not what he seemed… Ok, who are we kidding? No one saw that one coming!

4. Veritaserum

A tool of the oh-so-evil Umbridge and respectable Dumbledore alike, this truth serum sure comes in handy when you want someone to spill their guts!

5. Owl post

Harry gets a lot of information from the outside world through his owl, Hedwig. Wouldn’t it be nice if you had a winged friend to send notes to people?
