safe liquids to use for 'pink eye' video?

[cheeky_chappie]

sure no worries. i'm going to be shooting a (i hope this is the right term!!) pink eye video i.e. models eyes are intentionally open when various (safe) liquids are dripped into them, causing a kind of film over eyes even when model opens and closes eyelids.

i've seen this theme before years ago but the liquid was evidently supposed to be you know what however i hope to use 4 or 5 everyday liquids that are obviously just what they are e.g. tomato sauce.

can you advise any liquids i should definitely steer clear of? although the end goal is to have bloodshot eyes this obviously has to be achieved safely. i suppose even something that might seem safe enough might not be suitable for dripping into someones eyes!!

advice welcome

i hear LSD is safe, but probably not what you are looking for
