I first did this years ago. I got little herb/spice jars, filled them with random things, like ‘sticks’, ‘sand’, ‘rocks’, and sneaked them into people’s pantries at parties.
My favorite was a household of two couples. At their housewarming party I did this with sticks. The best thing was everyone saw it and everyone was confused, but they all just assumed it was some weird quirk of someone else.
Apparenlty it was found out like this:
Picture 4 housemates milling around the kitchen. One is cooking and opens the pantry, sees the sticks.
“Hey I was wondering. WHY do you have a little jar with sticks in it?”
“It’s not mine. I thought it was yours.”
Everyone stares at each other for a few seconds, and then all exclaim “AVRIL.”
So I did this again with Hair and Sticks, at a friend’s house the other day where we were invited for lunch (the lunch was awesome curries. 5/5. Would eat lunch there again).
The main thing is to not get caught. I deliberately wore a dress with pockets in it (POCKETS ON DRESSES ARE USEFUL, Y’ALL) and had to wait until their household were a) not in the kitchen area and b) looking away from the kitchen area.
I did it but it took a lot of waiting. MUCH easier at a party with people milling around distracting everyone.
Later that day I was sent this:
I also sneaked into the en-suite and left the ‘hair’ in the vanity there. It seemed a more appropriate place for it than a pantry. That went a few days without being found.
