I've played a few tricks on people in the past with a tube of superglue in the past. Once, in the 80s after gluing a dime to the sidewalk, someone came back with a hammer to get it off.
In today's world - with uploads and video channels - I've just thought of a great idea for a YouTube video.
Superglue a plastic bitcoin onto the sidewalk and see how many people try to prize it off.
Further up the sidewalk, paint/chalk 12 real seed words, in the right order, that point to 100,000 sats of Bitcoin and see which gets taken first. I'm guessing the plastic coin will be retrieved in a regular neighborhood every time.
It'd be great to upload a video of how passersby in NYC, SF and Austin (and cities around the world) compare and put the videos onto YouTube for us all to watch.
