Ok so this is weird. I have done DIY for a little bit ( a few months) and I got the carto tank from mad vapes, some fluxomizers from gotvapes ect that I have been using my juices in and they work great.... but then I made of some rootbeer I got from onestopdiyshop.com and it tastes good. I was happy with it so I filled up a brand new tank, took a few puffs and set it down. When I came back 10 min later the plastic was shattered. Hmmm, ok thats weird I thought but oh well, I am just out a new tank thats all. Then I put it in a fluxomizer and I had no problems, vaped on it all day. I got home tonight and added it to a Clear eGo Dual Coil Mega cartomizer and put it on an eGo took a hit and set it down. Looked at it a few min later and its cracked. I have used 30ish of these and never cracked one. Here I am thinking "Man this is starting to get weird, and its only my RootBeer flavor". Then I take off my drip tip on my fluxomizer cartomizer and I notice the bottom of the drip tip is melted..... Now in the 2 years (ish) I have been vaping I have NEVER melted a drip tip. And its melted in a way like if you put plastic into a chemical (Acetone ect...) But the actual plastic of the fluxomizer is holding up fine. Now call me crazy but this is too weird for it to just happen with all these. I have not changed my nic, pg/vg ect, only the flavor, and I am making it the same as I do all my other flavors. Any ideas on why rootbeer flavor would cause this to happen. Needless to say I have stopped vaping it for now.
