Corn Pops

Sometimes exploding or pop-corning droplets also appear which give rise to vivid star-shaped spark trails. 

Popping corn uses gas laws to explain the expanding popcorn hull.

One of the issues that concern liquid feedstock cracking operations is a higher rate of fouling. This is not only a consequence of heavier coke forming precursors, but also as a consequence of long lived free radicals which act as agents for the formation of a polymer (often referred to as pop-corn polymer) in the primary fractionator and downstream units. For instance, free radicals based on styrene or indene have sufficiently long half-lives to pass from the pyrolysis section into the primary fractionator. These can concentrate in this unit and produce polymer (free radical polymerisation) when sufficient amounts of suitable olefins are present, in particular styrene itself and di-olefins such as cyclo-pentadiene or butadiene. 

Cavernomas maybe calcified and have a typically pop-corn like appearance on MRI Surgical resection is recommended for cavernomas presenting with symptomatic hemorrhage in accessible and non-eloquent locations... 

Fig.2.13a-d. Non-enhanced CT revealed a calcified lesion close to the foramen Monroi (a), T2 delineated a pop-corn like structure typical for a cavernoma (b). After contrast injection (c) an associated developmental venous anomaly was seen in close vicinity. Gradient echo at 1.5 T sequence clarifies the large extent of the hemosiderin deposition of the cavernoma (d)... 

Observation in an Experiment students observe whether the volume of popped corn is greater when the kernels have been soaked in water prior to popping or when they have not. 

Clayey Uruguayan soils from different places were analyzed using the step by step guide. Several described items as pop corn features, calcic carbonate, surface cracking, damage to buildings, plastic and sticky appearances were observed during field works. Cut slopes show pop corn feature and carbonate concretions (Fig. 42.2a, b) and the soils in these...
