Unhiding things
If you nick a pound coin off someone, and put it on top of a prittstick in the middle of the table, they will never find it. Ever.
Technically, this theory has only been tested once, on Hardeep. But it worked; he spent an entire science lesson growing more and more furious with us for hiding his pound coin. We spent the entire lesson laughing ourselves daft and staring blatantly at the shiny pound coin sitting proudly atop the prittstick in plain view.
