Talk:Thermal grill illusion

Picture of the apparatus?
I think it would be good to have a picture of the device used to produce the illusion, even better if it shows it in use. --TiagoTiago (talk) 01:54, 18 November 2011 (UTC)

Three-glass experiment
The hedge "for some people" was added by someone who had tried the experiment themselves and failed to reproduce it in this edit (personal communication). Is there a reference for this experiment that could be cited? Kmill (talk) 03:22, 26 September 2021 (UTC)
