Watermelon Bubble Blast by Fruza is a 50/50 shortfill e-liquid that brings together two flavour profiles in one 100ml bottle. It's designed specifically for MTL (mouth-to-lung) vaping, which means it works brilliantly with smaller pod kits and starter devices. The shortfill format gives you the flexibility to add your own nicotine shots, letting you control the strength to match your preferences. Whether you're new to vaping or you've been doing it for years, this nicotine-free base gives you a solid foundation that's ready to customise, and you can grab yours today at Grey Haze.
The 50/50 blend, that's 50% vegetable glycerin and 50% propylene glycol, creates a thinner viscosity compared to higher VG shortfills. That's actually the whole point. It means better throat hit, quicker nicotine absorption, and it won't gunk up your MTL coils as quickly. You get the watermelon and bubblegum flavour without the hassle.
Right, here's the thing about shortfills. They're not just regular e-liquid in bigger bottles. They're partially filled on purpose. You get roughly 80% of the bottle filled with flavoured liquid, and the rest is empty space waiting for your nicotine shots.
Why? Back when the TPD regulations came in, manufacturers couldn't sell nicotine e-liquid in bottles larger than 10ml anymore. Shortfills got round that by shipping nicotine-free juice in bigger bottles. You add the nicotine yourself using nic shots, little 10ml bottles of concentrated nicotine that you mix in.
With a 50/50 shortfill, you're getting a blend that's specifically formulated for MTL kits. The higher PG content means better flavour delivery and a proper throat hit, which is what MTL vapers actually want. It's thinner than sub-ohm shortfills, so it won't cause problems with your coils or wicking.
Adding nicotine to your shortfill is straightforward. You don't need to be a chemist. Most people add two 18mg nic shots to a 100ml bottle, which gives you roughly 3mg nicotine strength. If you want 3.3mg, use two 20mg nic shots instead.
Just pop the nic shots into the bottle, screw the cap back on, and give it a good shake. That's it. Leave it for a few hours if you can, the nicotine settles better that way, but honestly, you can vape it straight away if you're impatient.
The beauty of doing it yourself is you're not paying for pre-mixed nicotine e-liquid, which costs more. You're buying the flavour base at a lower price and adding nicotine on your terms. If you want to go lower strength one week and higher the next, you just adjust your nic shot count.
Watermelon Bubble Blast does what it says on the tin. You get a watermelon hit upfront, followed by a bubblegum sweetness that lingers. It's not overly complex or trying to be something it's not. The flavour comes through cleanly on MTL devices because of the 50% PG content, that's what carries flavour molecules effectively.
On a pod kit, you'll notice the flavour is consistent from the first puff to the last. There's no weird chemical aftertaste or anything dodgy happening. The watermelon stays present, and the bubblegum provides that sweet finish without being cloying. Some people might find the sweetness a bit much if they're not into dessert-style juices, but that's personal preference.
Vapour production is moderate, which is exactly what you want from a 50/50 blend. You're not getting massive clouds, that's not what MTL vaping is about. You're getting a satisfying mouth-to-lung experience with decent flavour and a proper throat hit that feels like smoking, just without the tar and ash.

If you're using an MTL kit, 50/50 is genuinely the only shortfill format that makes sense. Higher VG shortfills (like 70/30 blends) are designed for sub-ohm devices with bigger coils and more power. They're too thick for MTL systems, they'll flood your coils, cause leaking, and generally cause a headache.
50/50 shortfills are lighter, they wick better, and they work with the way MTL pods are designed. You get better flavour too, because propylene glycol carries flavour molecules more effectively than vegetable glycerin does. It's not complicated, it's just the right tool for the job.
Cost-wise, buying a 100ml shortfill and adding your own nic shots is cheaper than buying pre-made 10ml bottles. You're paying for the flavour concentrate, not the nicotine markup. Over time, that adds up, especially if you vape regularly.
Yes, absolutely. The 50/50 blend is specifically designed for beginner-friendly MTL kits and pod systems. Once you add your nic shots, you'll get a nicotine strength that feels familiar if you're coming from smoking. The flavour is straightforward and enjoyable without being overwhelming.
That depends on how much you vape. A typical MTL vaper might get through 10-15ml per day, so a 100ml bottle could last around a week or more. Since it's nicotine-free until you add shots, you're essentially buying a bulk flavour base that you can stretch across multiple nic shot additions if you want.
Not really. Sub-ohm devices need higher VG e-liquid (usually 70/30 or higher) to produce proper vapour and avoid flooding. The 50/50 ratio is too thin for those systems. Stick with MTL or pod kits for this one.
The nicotine concentration is slightly different. Two 18mg shots in 100ml gives you roughly 3mg final strength, while two 20mg shots gives you 3.3mg. It's a small difference, but if you're sensitive to nicotine, you might notice it.
No, you can vape it as-is if you want zero nicotine. Some people do this for flavour-only vaping or to reduce their nicotine intake gradually. It's your choice, that's the whole point of shortfills.
