Created by a Japanese data researcher, the thermal mapping table uses a projector with a thermal imaging iPhone case.

When items are placed on the table, the case identifies even slight changes in temperature to reveal when a beverage is safe to drink.

Designer Ken Kawamoto used a Flir One thermal imagine iPhone case, which costs around £250 (£390). 

In a video, a glass of ice water is shown turning the table blue, while a glass of hot water is shown turning it red.

Kawamoto also pours cold and hot water into a tray, to see how the liquids combine, and shows what a MacBook’s battery looks like under thermal imaging.

Projection mapping uses video projectors, but instead of projecting the image onto a flat screen it maps the light onto any surface.

This light scatters the pixels of an image, and turns any surface – in this case, a table - into an interactive display.

The process is also known as spatial augmented reality and video mapping, and is typically used for adverts.
