Every year, I get my youngest sister a prank gift for Christmas. Ranging from coal, to duct tape wrapping, to a box wrapped in a wrapped box x8, to my magnum opus last year: a box rigged with poppers to go off when it's opened. 

But now, I've burned my best idea and don't know how to top it. And it's her senior year of HS. The last year of "childhood". Any good prank gift ideas?

I don't have a great one besides combining a few past years. I'm scrambling for sure.
