Wow thats awesome! Well done man! Where do you get the Ultrasonic bath?Did an experiment yesterday (after reading about it on http://www.e-cigarette-forum.com) Speedup steeping in ultrasonic bath. When first mixed (RY4 5.5ml + Cherry 7.3ml + Menthol 7.2ml) the cherry was totally overwhelming and the menthol gave me a BALL-KICK in the throat. No juice left and can not wait for 2 - 3 weeks. I know they use ultrasonic devices in chemical labs to mix stuff, so I put the freshly mix in the ultrasonic bath and kept the water temp under 50C so as not to oxidize the nicotine. In the 3 hours plus cool down time I almost took a stinkie. Well I was surprised beyond all stinkies when I took the first vape - it worked; the cherry and menthol was very subtle afterthoughts and I could "taste" the RY4 for the first time what it's suppose to be. No more KICK-N-THE-BALLS throat hit, but as I like it. Vaped myself in a stupor last night.
