How do I do smoke tricks?

[CheatSource]

So if you go on Vine you see people do a lot of smoke trick vines along to music. I want to know what people are using to make the smoke and where can I get them. Some Amazon links would be nice too.

They are using vapes,ecigs/hookah pens, or hookah.(all have no nicotine no tobacco unless u get it with iit)
Amazon only sells hookahs, they dont sell pens or ecigs.


Heres a cheap link to a hookah starter kit(i do recomend a pen or vape though):
