Brainley and Dobbsey are in the lab. Dobbsey has an erlenmeyer flask full of tea.

Dobbsey: Professor, did you forget to refill the ice tray in the lab freezer? My iced tea is alarmingly devoid of ice.

Brainley: No matter! My latest invention, Ice 8.7^TM, will solve your problem in short order!

Brainley drops a crystal into the flask. Bolts of electricity branch out throughout the liquid.

Brainley: By simply adding a crystal of Ice 8.7^TM to your beverage...

The crystal and electricity suddenly transform into glowing ice cubes.

Brainley: ...you can catalyze a chemical reaction converting any water to ice.

Dobbsey: That's amazing! But why doesn't all the liquid freeze over?

Cut to a theoretical shot of a frozen-over "iceball Earth".

Dobbsey (voiceover): For that matter, why isn't there the risk that the entire planet ends up frozen due to a runaway chain reaction?

Cut to a shot of the surface of an ice cube. A hard hat is sitting on the ice, and "Construction" tape surrounds the area. A sign proclaiming "Ice Under Construction" is covered over by a sheet of paper with the text "On Break" scribbled on it.

Brainley (voiceover): Well, as it turns out, the ice crystals are very lazy.
