Are you over 18? Any particular reason you need your dad's approval? There is a great case to be made for vaping for a former smoker, but that's really not you. I don't really have an arsenal of great reasons to vape for experimenters with vaping/smoking that aren't really addicted to anything yet. No one knows the long term effects of vaping, but it's pretty clear that it's a great deal safer than smoking, long term data just isn't there yet.
I don't tend to recommend that "experimenters" starting vaping routinely, it's not a good idea IMO. I suppose if you don't start smoking and you think you might if you don't start vaping, that's a decent reason. But really not otherwise. You could look around the forum and maybe do a search, there are a lot of scientific articles that show that vaping is... safer than smoking, by a large margin, there are even collections of articles. You aren't going to find one that says that picking up vaping as an almost-never-smoker is a great idea though, I can pretty much guarantee that.
If you must vape (oh, how I hate typing that sentence in these situations) then at least use 0 nic juices. FDA has approved most flavors for INGESTION, not inhaling (though I think there may be one or two that have) so inhaling flavors is also a bit of an unknown, though people don't seem to be dropping dead over it, but again, no long-term studies. So, I'd suggest unflavored, no nicotine vape as the safest option, if you must vape.
Why not find something else to present to your dad that will really thrill him, not vaping? Like, learn the flute, you will be inhaling and exhaling, it will be fantastic and improve your lung capacity. Take up a serious exercise habit. Etc., etc.
Good luck.
