Welcome to Teaser [TS] Tuesday. The shortened version of the name, TST, comes from a scientific theory known as Transition State Theory. This theory is used to understand how chemical reactions take place, and explains the rates of these reactions.
In terms of our subject of teaser trails in Kpop, these theories are very apt. TS trails are created to cause a reaction and we will be looking to explain what the teaser media tells us, what it is that causes these reactions. Hence our TST molecular logo.
