Laminar flow reactor each other like cards. When analyzing fluids with the same viscosity ("thickness" or "stickiness") but different velocity, fluids are typically characterized into two types of flows: laminar flow and turbulent flow. Compared to turbulent flow, laminar flow tends to have a lower velocity and is generally at a lower Reynolds number. Turbulent flow, on the other hand, is irregular and travels at a higher speed. Therefore the flow velocity of a turbulent flow on one cross section is often assumed to be constant, or "flat". The "non-flat" flow velocity of laminar flow helps explain the mechanism of an LFR.

What It Is to Burn with boiling liquid. Doherty said they "just wanted some cool imagery". The art direction and design were done by P.R. Brown, who also did the photography with Kris McCaddon. Initial pressings of the album contained a demo version of "What It Is to Burn", produced by Chris Fuderich. It was replaced on later pressings with a re-recorded version, produced by Trombino. These later pressings were available from June onwards. The UK edition, released on June 2, included an acoustic version of "Letters to You" and the demo of "What It Is to Burn" as bonus tracks. Following the album's release,
