well i e mailed him and this is what he said:
Hi Jon,
You will find that we typically will leave our liquids as concentrated as possible in an effort to preserve flavor strength and allow the customer to receive the most bang for their buck. Unfortunately, depending upon the device and method of use, this will dance on the edge of being to thick for some vaporizers. Dark liquids typically contain thicker flavorings and it is common that folks will want to thin these a bit to customize for their own device. You'll likely find this to be the case with your Root Beer and Smore (Eggnog is usually not an issue but may be in your device).
In order to thin down your liquids you can simply add a few drops of distilled water to the bottle and shake it up until a consistency is reached that works best for you. Typically the amount needed will not be enough to significantly decrease flavor or the nicotine strength. Even thinning them down the dark liquids will still remain to be higher maintenance however and you will probably want to blow your atty out every few hours. I personally love the darker flavors and will typically direct drip them (drip 2-3 drops directly onto the bridge of the atomizer rather than fill carts). By keeping the atomizer wet I am able to get several hours of use prior to having to blow them out.
Hope that helps and please let us know if we may assist further in any way,

i will thin them out a little and try again. i did blow out the atty like he said and it did help.
