@Hipporex This sign is in a section of the aquarium called 'Polar Play Zone', which is aimed toward young kids. Part of this is that signs explaining opposites are everywhere. This one is infamous because it is actually dangerous for the kids. If you touch the 'cold' sign, it fells slightly chilly to the touch. But if you touch the 'warm' sign, even for a fraction of a second, you could almost burn yourself! I can't believe they would put that in a children's area.
