Transparent debris effect

A transparent debris effect is a reaction in which a Herschel or other active region destroys a still life, then later, having passed through the place where the still life was, recreates the still life in its original position. The transparent block reaction, shown below, is an example of this phenomenon.

The transparent block reaction is a certain reaction between a block and a B-heptomino in which the block reappears in its original place some time later, the reaction having effectively passed through it. It was found by David Buckingham in 1988. It has been used in some Herschel conduits, and in the gunstars.
