That eyeshadow potion stuff sounds totally unnecessary: I use eyeshadows as liner a lot just by mixing with good ol' H20, what's wrong with that?
As for the glitter eyeshadow gel.... it sounds and looks AWFULLY like a brilliant little budget product I have been using for years, and which costs a fraction of the price.... it's made by an "alternative" British cosmetics company Stargazer*....

- Go to Cosmetics
- Then "Face and Body Glitter"
Item description:-
"The Glitter Gel range has been updated with a new applicator and new shades. The applicator allows a very smooth application of the glitter to the skin. Our Glitter Gel can be applied straight around the eyes, on the face and body with amazing results. "
Price: £3 sterling (which is like, $5 ish I think)
See? Looks practically identical dunnit? Even the applicators are alike!
- Unfortunately Stargazer seem to have discontinued the two shades I liked the best (irridescent gold/green and irridescent blue: they had finer glitter than the others, so gave a more intensely glittering finish - if you see a tube of either of these snap 'em up!!!) but the of the ones they're still making I can tell you that the irridescent white and the multi colour are both pretty good.
You can layer the gel on top of other shadows (this is a good idea for the larger particled glitter ones as the base gel is clear - I usually use a black shadow mixed with a little water to put the gel on top) and I sometimes even top them up with (eyesafe!) loose glitter while the gel's still wet for a totally "discoball" eyelid.
The other one I'd strongly recommend is the red, but personally I use it as a topcoat over blotted red lipstick** rather than on eyes - it tastes nasty when it goes on, but once dry the taste disappears and it stays really well - it gives a really, really pretty "ruby slippers" look too.
This is a UK brand that can be bought from goth/hippy shops here quite commonly. I have a friend whose online store stocks the stuff too and I believe she'll happily ship to the states, if anyone's interested I can find out for ya...
* nb - most of Stargazer's products are really awful I'm warning you! the exceptions to that rule are their fake eyelashes (fun and well priced), their pigment style eyeshadow, and this glitter eye gel, which is a great little buy especially at that price.
**nb - I don't know if this eye glitter gel is strictly lipsafe, so be aware of that if you try this one out! It's definitely marked as eyesafe though.
