 ===== About =====
 Corona discharge wands use a high frequency electric field to ionize the surrounding air over a very short range. In principle, their operation is similar to a tesla coil, which accumulates charge until a high enough voltage is reached to produce a spark. Each spark produces a small amount of plasma (as indicated by the light produced) which creates active ions that increase the surface energy of polymers.
+The primary reason to increase the surface energy of a polymer is to make is stickier. For instance, many paints, inks, and functional biological & chemical reagents will adhere to corona-treated polymers much better than untreated polymers. Additionally, some polymers, such as PDMS, will stick to each other after corona treatment.
