I've been somewhat shocked at seeing these forehead thermometers being used for screening. Forehead thermometers are not accurate. https://www.ncbi.nlm.nih.gov/pubmed/24127699 https://www.ncbi.nlm.nih.gov/pubmed/24127699 I challenge HN's readers to devise ways to defeat a forehead thermometer. IF we had a hackathon around this idea, how long until somebody devises a method of communication via forehead thermometer reading manipulation?

Smear some alcohol on your forehead before the check, the phase change as it evaporates will drastically decrease the local temperature where it's applied.
