## Description

Take laughs with Lie Detector Prank - Polygraph. This extension delivers a realistic polygraph-style prank: a fingerprint scanner interaction, authentic sounds, and a dramatic 'TRUTH or LIE' reveal. It works offline, is free, and supports 15 languages for international fun.

How it works: ask a question, have a friend place their finger on the scanner, and watch the polygraph animate as it 'analyzes' their pulse. Use for parties, Truth or Dare twists, or couples games. Includes a safety disclaimer that it’s a prank and that results are generated for entertainment; no real lie detection. Quick setup; no subscription required.
