In the following video Canadian YouTuber AvE demonstrates that Wonder Bread can be transformed into carbon foam – a substance that is said to be similar to the material used to cover the space shuttle.
The process is reportedly the same as making charcoal, and involves putting the bread in a very hot, oxygen-free container until it is blackened. The bread’s tiny holes are retained in the final product, resulting in a type of foam with “incredible insulating properties”.
AvE states that the substance has an exceptionally high electric resistance and can withstand temps of up to 6,600 degrees Celsius (or about 11,900 degrees Fahrenheit) without melting or burning. Instead, it sublimates, or instantly turns into gas.
Scientists working on a recent study for ACS Applied Materials and Interfaces discovered that carbon foam made from bread “is mechanically stiff, can shield against electromagnetic interference and is much less flammable than current carbon foams.”
In other words, this is a cheap and effective way to make a supremely useful material. See how it’s done in the video below.
