When many people hear molecular gastronomy, they think of culinary foams, originally introduced by Ferran Adria at El Bulli. In case you’re fed up with the foams, here’s a T-shirt to express your feelings:
Personally, I can’t even say I’ve taste any of these foams yet… Guess I’ll wait a little with the T-shirt then
An object does not need to be superconducting to levitate. Normal things, even humans, can do it as well, if placed in a strong magnetic field. Although the majority of ordinary materials, such as wood or plastic, seem to be non-magnetic, they, too, expel a very small portion (0.00001) of an applied magnetic field, i.e. exhibit very weak diamagnetism. The molecular magnetism is very weak (millions times weaker than ferromagnetism) and usually remains unnoticed in everyday life, thereby producing the wrong impression that materials around us are mainly nonmagnetic. But they are all magnetic. It is just that magnetic fields required to levitate all these “nonmagnetic” materials have to be approximately 100 times larger than for the case of, say, superconductors. This experiment was conducted at the Nijmegen High Field Magnet Laboratory.
This is slightly off-topic, but take a look at these two videos on mechanical gastronomy. First one is a lego-machine that opens a bottle of beer. The second one is a Rube Goldberg (homepage, Wikipedia) machine that pours a beer (jump to 2:10 if you want to skip the intro and just watch the action). Rube Goldberg described his cartoons as “symbols of man’s capacity for exerting maximum effort to accomplish minimal results”, but has since given name to complicated machines that perform simple tasks!
Heston Blumenthal was recently featured in “Private Eye”, a british satire magazine (found via Aidan Brooks). They included the following recipe for boiled eggs:
A further discussion of boiled eggs from the perspective of molecular gastronomy is found here.
