The infofuse – encoding messages using colourful fire

The infofuse – encoding messages using colourful fire | Digital #MediaArt(s) Numérique(s) | Scoop.it

For many of us, the most memorable bits of school chemistry classes were lessons where we ignited metal salts over a Bunsen burner to produce brightly coloured flames, from the lilac of potassium to the distinctive red of lithium. Now a group of chemists from Harvard University have found a way of using these colourful flames to transmit coded information.


Working in the lab of legendary chemist George Whitesides, Samuel Thomas III has developed the ‘infofuse’, a strip of flammable paper patterned with metal salts. As the strip burns, the metals change the colour of the flames, creating coded pulses of light that can be used to send messages. It’s a vibrant, visual equivalent of Morse code and as a test-run, they used their infofuses to transmit the message, “LOOK MOM NO ELECTRICITY”....

Rubens' Tube is an awesome demo and here we take it to the next level with a two-dimensional 'Pyro Board'. This shows unique standing wave patters of sound in the box.

The pressure variations due to the sound waves affect the flow rate of flammable gas from the holes in the Pyro Board and therefore affect the height and colour of flames. This is interesting for visualizing standing wave patterns and simply awesome to watch when put to music. Thank you to Sune Nielsen and everyone at Aarhus for sharing this demonstration with me! And thanks for having me at your conference.
