Send one link. Watch ten seconds of confusion. Walk away. 
Six free sites, arranged by who deserves it.
For the friend who opens anything → 
creepylink.com
No jump scare, no flashing screen — just a link behaving in a way a link should not. The quiet ones are the ones that get forwarded with no message at all.
For the office know-it-all → 
hackertyper.net
Their keyboard becomes a hacking movie: type anything, “access granted” appears. The illusion belongs to the person typing, which is why it lands every time.
For the colleague who left the laptop open → 
fakeupdate.net
A full-screen Windows update that never finishes. The most believable of the lot — people genuinely sit and wait.
For a sibling or a roommate → 
geekprank.com
Fake virus alerts, cracked screens, blue screens, all full screen. One site, a dozen different panics.
For someone bored for five minutes → 
theuselessweb.com
One button, endless pointless websites. Harmless, instant, works on any screen.
For a long quiet scroll, not a prank → 
floor796.com
A pixel building with a thousand animated rooms. It is not a joke — it is a place, and it holds people longer than any prank above.
The 10-second setup
The two-second setup: press F11, hand the laptop over, step back.
open link → F11 → hand over
10 sec fullscr enjoy
One shot only? Creepylink. It has no graphics to give it away.
Desktop only — on a phone the effect dies instantly. Save them for someone about to leave the room.
