The menthol burst ball found in Camel Crush & Kool Boost now found in Camel Menthol Lights. The ball, hidden inside the filter, when squeezed, breaks and releases a powerful menthol goodness. The menthol lights cigs are the same as before but can now have an even more powerful menthol flavor. I think this is great for the menthol lights cigs as they weren't mentholly enough before. I also found that squeezing the ball early when smoking the cig, the powerful menthol flavor will last to the end...of the cig. To acheive the best experience and to get most of the burst, squeeze the ball til you hear it pop, you'll feel it pop too, then rotate the filter by squeezing it slightly like your rolling it to loosen the filter, allowing the burst of menthol to flow easier into your mouth.
